Return to The Config.sys Documentation Project Main Page

The Base Device Drivers are needed by OS/2 to install elementary services, like your hard disk, keyboard, etc. The Base Device Drivers are the first entries from the config.sys file that are loaded during the boot. They are not loaded in the same order as they appear in the config.sys file. They are loaded dependant on their file extension.

Here is the order of loading for the file extensions.

  • *.SYS
  • *.BID
  • *.VSD
  • *.TSD
  • *.ADD - Adapter Device Driver
  • *.I13
  • *.FLT - Filter
  • *.DMD - Device

If the CONFIG.SYS contains several files with the same extension, those files will be loaded in the order they appear in the CONFIG.SYS file.

The Base Device drivers must be located in the root directory in the \OS2 directory or in the \OS2\BOOT directory. If you set up a Base Device driver in your CONFIG.SYS please use only the name of the driver without the path. The following pages describe these entries:

SCSI

AIC7870.ADD

Driver for the Adaptec AHA-2940 PCI SCSI host adapter and the AIC-7870 controller. 

BASEDEV=AIC7870.ADD <parameters>

Universal Parameters:

  • /ET

Allow embedded targets. This parameter indicates that the ADD should assume that all targets have more than one logical unit (LUN) defined.

  • /!ET

Do not allow embedded targets (DEFAULT). This parameter indicates that the ADD should assume that all targets have only one logical unit (LUN) defined.

  • /V

Load driver verbosely. This parameter will display the driver name as well as the version number and Adaptec copyright if the driver loads successfully. Information on all targets found in the system will also be displayed.

  • /PCIHW

Enables driver to access PCI configuration hardware registers. This switch is implemented because in some PCI systems, accessing PCI configuration space through PCI BIOS function calls causes problems. This switch is enabled by default. New with Version 3.02

  • /!PCIHW

Disables the PCIHW switch. This parameter will cause the driver to access the PCI configuration space through PCI BIOS function calls. New with version 3.02

General Unit Parameters:

  • /I

Ignore the specified adapter. This allows another driver to share the adapters that the ADD would normally use.

  • /DM

Enable DASD manager support (DEFAULT). This parameter allows OS2DASD.DMD to control the specified target(s) if they are identified as DASD (hard disk) devices.

  • /!DM

Disable DASD manager support. This parameter prevents OS2DASD.DMD from controlling the specified target(s).

  • /SM

Enable SCSI manager support (DEFAULT). This parameter allows OS2SCSI.DMD to control the specified target(s) if they are identified as NON-DASD SCSI devices. All SCSI hard drives will be controlled by OS2DASD.DMD.

  • /!SM

Disable SCSI manager support. This parameter prevents OS2SCSI.DMD from controlling the specified target(s).

  • /TAG:n -- n=1-16.

Specifies the maximum number of tagged commands for all target devices on the host adapter (1-16). A value of 1 disables tagged queuing. The maximum number allowed is 16. (The default is 8.)

  • /UR

Enables reporting of under runs (DEFAULT).

  • /!UR

Disables reporting of under runs.

TIP: If Warp doesn't recognise the AIC7870 Driver add the parameter /A:n n=Number of Controller and /TAG:n n=number of PCI-Slot to AIC7870.ADD. It seems that the version 2.2 of the Adaptec 2940 driver does not work correctly with RSJ, but version 2.11 works fine.

Parameter
  • [Universal Parameter] - An option that applies to all adapters controlled by the driver.
  • [Adapter ID] - /A:n, where n is the number (zero relative) of the adapter installed in the system. The adapter ID is determined when the driver is loaded based on the order that adapters are found in the system. (Refer to the Configuration Examples in the "General Unit Parameters" section below for information on how to use this option.)
  • [Unit Parameter] - Modifies the behavior of the selected host adapter.
  • [SCSI Target ID] - The targets to which the Unit Parameter will be applied. This parameter may be a single ID (d) or list of IDs (d,d,d).
Universal Parameters
  • /ET

Allow embedded targets. This parameter indicates that the ADD should assume that all targets have more than one logical unit (LUN) defined.

  • /!ET

NOTE= Intel Errata #8511 lists known data integrity issues with the processor cache on the Saturn-1 chipset (82424TX). For this reason, Adaptec recommends that processor cache be disabled via the CMOS setup to avoid data corruption. For more information, see Intel Errata #8511. You may get this from Intel's FaxBack system at or .

There are installation problems when installing on the maximum hard disk drive partition size supported by OS/2 v3.0. On OS/2 v3.0 it is a known problem. Refer to IBM for further info. IBM's APARs PJ15988 and PJ 6151 deal with this issue.

There are known installation problems installing OS/2 Warp v4.0 on a Micron (LSI chipset) 64 bit PCI system.

There are known installation problems installing OS/2 Warp with 8MB of RAM unless all the third-party basedev statements are removed from config.sys.

There are known installation problems installing OS/2 using two SCSI host adapters on a "Marl" motherboard. Whenever you have a LVD HDD on one Ultra160 host adapter and a HDD, CD-ROM, and removable Syjet on another UltraSCSI host adapter, Syjet conflicts with the CD-ROM and the system is unable to access the CD-ROM.

This version of the Ultra160 Family Manager Set driver supports the AIC-7892/99 Family of Host Adapters. Adapter numbers are first assigned to boards with their BIOS enabled. The numbers are assigned from lowest BIOS address to highest address. Any remaining boards are assigned numbers by scanning slots. Each slot is a combination of a bus number and a device number pair starting from lowest to highest numbers, and the adapters are assigned a number in the order they are found.

Example: 

Bus 0, device 0 assigned as adapter 0; Bus 1, device 1 assigned as adapter 1, etc.

There are no switches for controlling OS2ASPI.DMD directly. IBM did not define them in their specification and Adaptec cannot be sure that other host adapters will have the same switches. OS2SCSI.DMD will only allocate devices when a device driver requests it, but this will prevent OS2ASPI from accessing it. There is nothing in the ASPI specification regarding device allocation so OS2ASPI must rely on other managers to fairly share targets. This should only be a problem if you have two drivers that use different managers and you want them both to access the same target at the same time.

Do NOT disable DASD manager access to target 0 if you are booting from your SCSI host adapter. This will prevent the system from booting!

Fault Tolerance is supported in the driver. However, ABORT and SCSI BUS RESET will only work for targets that are properly behaved.

IBM does not support installing the operating system onto magneto optical devices. Additionally, OPTICAL.SYS (OS/2 3.0) or OPTICAL.DMD (OS/2 4.0) allows magneto optical devices to be supported as though they were large floppy devices.

LOCKDRV.FLT allows removable media such as MO's to be supported as though they were fixed hard drives. It is not possible to install OS/2 3.0 on drives with capacity greater than 8 GB, nor in a partition greater than 4 GB.

OS/2 will allocate the SCSI devices as the order in CONFIG.SYS if two drivers (such as the AIC7870.ADD and AICU160.ADD) are loaded. OS/2 will assign drive letters for SCSI devices first then IDE devices.

/S=0123 ;same as above
/S:0123 ;same as above
/S=0,1;23 ;same as above
  • /U[=ID-List]

Forces Uni-Directional transfermode. Optionally you can specify the target-id's, otherwise this parameter is valid for all targets.

  • /B[=ID-List]

Forces Bi-Directional transfermode. Optionally you can specify the target-id's, otherwise this parameter is valid for all targets.

  • /US[=ID-List]

Forces Uni-Directional Safe transfermode. Optionally you can specify the target-id's, otherwise this parameter is valid for all targets.

  • /BS[=ID-List]

Forces Bi-Directional Safe transfermode. Optionally you can specify the target-id's, otherwise this parameter is valid for all targets.

  • /EPP8[=ID-List]

Forces EPP-Byte mode. This parameter can help to solve problems related to some EPP port hardware. Optionally you can specify the target-id's, otherwise this parameter is valid for all targets.

  • /PORT=xxx

xxx=378, 278 or 3BC, this parameter selects the I/O address the driver should use. Normaly you don't need this parameter, because the driver automatically detects the port, where the SCSI cable is connected. If the driver fails to do this or in case of conflict with other adapter cards this parameter will force the driver to check only the given port address.

DC2974.ADD

Dawicontrol DC-2974 PCI SCSI Host Adapter 

BASEDEV=DC2974.ADD

Parameter:

  • /PORT=xxx

If you are working with several SCSI hostadapters, type in the adapter number (for PCI hostadapters, starting with zero) or the I/O address (for ISA hostadapters) as the parameter's attribute. In this case, you will have to start the driver by specifying the adapter number or I/O address resp. for every connected hostadapter separately. This parameter is not required if you are working with only one SCSI hostadapter.

  • /PS=x

This parameter controls the Power Save function by specifying the maximum inactivity period (from 1 to 60 minutes). If the set value is exceeded, any hard disks, removable disks and CD ROM drives will be switched off automatically. The relevant device will be started again when it is accessed later. Not setting this parameter means that the function is disabled.

  • /ID=x

x = hostadapter's SCSI ID. The SCSI ID of the hostadapter will be set automatically if this parameter is not specified. Valid SCSI ID values are 0 to 7. Hostadapters supplied with a SCSI setup ignore this parameter and use the setup settings instead.

  • /LUN

This parameter enables the device's support of several LUNs (Logical Units). However, most SCSI devices only have LUN 0 available to them so that you will need this parameter only for special cases. Host adapters supplied with a SCSI setup ignore this parameter and use the setup settings instead.

  • /!SN=x,..,x

This parameter defines the devices that are to run in asynchronous instead of in synchronous mode even if the device tries to switch into synchronous mode. Hostadapters supplied with a SCSI setup ignore this parameter and use the setup settings instead.

  • /SN=x,..,x

This parameter specifies the devices to be operated in Synchronous Data Transfer mode if this mode is supported by these devices. If you do not set this parameter only devices that can switch into synchronous mode themselves will be operated in this mode, all other devices will remain in asynchronousmode.

  • /!SM=x,..,x

Use this parameter to specify a list of SCSI IDs representing the devices that are not to be supported by OS/2's Device Manager. As a rule, all connected devices can be controlled by the SCSI Device Manager.

  • /!DM=x,..,x

Use this parameter to specify a list of SCSI IDs representing the devices that are not to be supported by OS/2's DASD Manager (Device Manager for disk drives). As a rule, all connected devices can be controlled by DASD Manager.

  • /Q

Suppresses all on­screen messages (including error messages) during driver installation.

NOTE: For using scanners please insert the following parameters in the adapter-settings /!SN=(Scanner ID) /!DISC=(Scanners ID) Example: the scanner's ID is 6: /!SN=6 /!DISC=6.

CWUSBD.SYS

Basic USB driver by Chris Wohlgemuth, based on the sources available on the DDK site. It does not have the feature set of the latest IBM driver downloadable with software choice. If you already have a (maybe better) working driver from there feel free to use that one. 

BASEDEV=CWUSBD.SYS

Parameter:

  • /V

Verbose, show some information while booting.

  • /I13

parameter could be used to delay USB host overtaking by USB driver stack until other device driver finishes required initialization operations and then send request to USBD driver to start USB service. It could be used to boot from USB floppy drive.

  • /REQ

This parameter controlls USBD driver initialization: driver at initalization time checks for listed host controller drivers and fails to install if none of listed drivers is loaded. Current version of USB stack supports the following parameter codings:

  • /REQ:USBUHCD$
  • /REQ:CWUSBUHC$ USBD driver is loaded only if UHCI compliant host driver is loaded
  • /REQ:USBOHCD$
  • /REQ:CWUSBOHC$ USBD driver is loaded only if OHCI compliant host driver is loaded
  • /REQ:USBUHCD$,USBOHCD$,CWUSBOHC$,CWUSBUHC$

USBD driver is loaded only if one of OHCI/UHCI compliant host drivers is loaded. This most general form of parameter and must be used in most cases.

CWUSBMSD.ADD

Enhanced USB mass storage driver by Chris Wohlgemuth which supports more (or other) devices than the IBM version. Support for READ 10 commands and better disk geometry handling. Can force external hard disks to appear as removable devices. 

BASEDEV=CWUSBMSD.ADD

Parameter:

  • /V

Verbose, show some information while booting.

  • /FLOPPIES:n

Number of floppy devices to be served (by default 1). In order to remove service the key value must be set to 0.

  • /A_USAGE:n

Parameter controls usage of 'A' drive flag for the 1st floppy device. The following values of n can be used:

  1. 0 - 'A' drive flag is not used;
  2. 1 - 'A' drive flag is used;
  3. 2 (default value) - 'A' drive flag is used only if there is no other device driver using this flag.
  • /MAX_FLOPPY

Parameter forces driver to report floppy device geometry with maximal sector count as floppy device physical geometry. With this parameter driver supports LS-120 media formatting but does not support XDF floppy filter features and vice versa.

  • /REMOVABLES:n

Number of removable media devices to be served (by default 1).

  • /FIXED_DISKS:n

Number of fixed disks to be served.

  • /CDS:n

Number of CD-ROM/CD-RW devices to be served (by default 1).

  • /REMOVABLE_AS_FLOPPY

System uses removable disks as partitioned volumes:

  • /FORCE_TO_REMOVABLE

Change external hard disks (for example Archos Jukebox) to removable. This may be necessary if a device anounces itself as a fixed disk but you want to use it as a removable device.

Tested devices:

Archos Jukebox Recorder 20 : This is a portable MP3 player which may also be used as a hard disk. It contains an In-System Design USB 2.0 bridge. The file system is FAT32. No DRM or similar crap.

DANIDASD.DMD

Replacement Driver for OS2DASD.DMD by Daniela Engert supports also Partiontypes 0E, 0B, 0C, 8F and 0F to ease the coexistance with WinXY and Linux.

For a discussion of these types see: Introduction, Partition types. 

BASEDEV=DANIDASD.DMD

Enhancements:

it supports extendedX partitions (type 0F) and Linux extended partitions (type 8F, even more clueless and useless than the Microsoft invented type 0F !) exactly the same as regular extended partitions (type 05). ExtendedX partitions are common today because of disks larger than 8GiB.

It supports FAT32 partitions (type 0B and 0C) exactly as IFS partitions (type 07, used by HPFS and NTFS). This way FAT32 partitions show up in "correct" order (w.r.t. the disk layout), and are assigned drive letters "as expected". PARTFILT.FLT is no longer necessary to make FAT32 partitions accessable, but Henk Kelder's FAT32.IFS is still required.

It supports FAT16X partitions (type 0E) exactly as big FAT16 (type 06) partitions.

Parameter (the driver supports all parameter the OS2DASD.DMD supports, so take a look at the link too) :

  • /AT:{,{,...}}

Must be two digits hexadecimal. Supports up to eight additional partition types as specified by by the user. This is meant for making hidden partitions (types 1x) or foreign file systems like Linux's ext2 (type 83) visible to the DASD manager. You have to tell DaniDASD.DMD the additional partition types by means of the parameter.

To summarize the notion of acceptable partition types, have a look at this table:

DASD manager partition types supported extended regular OS2DASD (pre-LVM): 05 01, 04, 06, 07 OS2DASD (LVM): 05, 0F 01, 04, 06, 07, 35, [+ other] DaniDASD: 05, 0F, 8F 01, 04, 06, 07, 0B, 0C, 0E, [+ other]

If an additional partition type is a "hidden" partition (1x), then a matching partition is propagated to its "not-hidden" counterpart (0x) and the acceptance rules above apply.

  • /BD:

Overwrites the boot drive letter assignment from fisrt boot stage. Can overcome boot problems which result in "can't operate hard disk" messages. This is common if OS/2 is booted without proper help of OS/2 Bootmanager which is required to notify OS/2 of the *correct* boot drive letter. If there is no boot manager with this capability available (e.g. when booting from removable media), or the boot manager fails to figure out the correct boot drive letter, you can tell DaniDASD.DMD the correct one by means of the parameter.

Example: in a mixed SCSI/EIDE environment with two SCSI adapters and and two different EIDE controllers involved (my current setup at home), the ATAPI ZIP250 drive gets assigned drive letter M:. To boot from this unit I have this line in CONFIG.SYS of the ZIP boot floppy 

BASEDEV=DaniDASD.DMD /BD:M
  • /MT:

can create a logical volume map independently from the physical volumes (partitions).

CAUTION when this option is in effect, DaniDASD no longer follows the old OS2DASD rule of accepting only the first acceptable partition in the primary partition table. Instead, the LVM rule of accepting all acceptable primary partitions applies!

After scanning the *fixed* disks for acceptable partitions following the rules above, a logical volume mapping is created from these partitions. This is done by means of a map table. This table lists the partitions which are to be given a drive letter in ascending, consecutive order, starting from drive letter C:. A particular physical partition is indicated by a two-letter code number>. Code "Aa" indicates the first partition on the first disk, "Ab" the second partition on the same disk, "Bc" the third partition on the second disk, and so on. The numbering of disks and partitions is given by the regular scanning order of DaniDASD.

Each entry in the mapping table must be unique, entries without an existing partition are ignored.

Example: 

BASEDEV=DaniDASD.DMD /MT:Aa,Ad,Ba,Bb

creates logical volumes C:..F: from the indicated physical partitions.

CAUTION this does *not* apply to removable media units! Their driveletters *always* follow the fixed disk ones.

NOTE DANIDASD.DMD does not work with OS2LVM.DMD, so use it in NON-LVM Systems only.

NOTE Together with DANIDASD.DMD the use of PARTFILT.FLT is no longer necessary to access FAT32 drives.

TIP You may also need a FAT32 aware FDISK.EXE. It was included in FP10 - FP14 for Warp4

TIP By Daniela Engert: You want to get rid of the LVM layer in WSeB/ACP/MCP/eCS ? I checked that on an old WSeB installation with only compatibility volumes, yesterday. I removed these two lines in CONFIG.SYS 

BASEDEV=OS2DASD.DMD // the LVM-aware DASD manager
BASEDEV=OS2LVM.DMD  // the LVM layer

and added this single line 

BASEDEV=DaniDASD.DMD // the non-LVM-aware DASD manager

The system behaved DASD wise like an ordinary Warp4 system afterwards. A Warp4 OS2DASD.DMD will do as well.

Rule of thumb: if your system doesn't suffer from any (possibly unknown) flaws, not a single command line option is required. The driver adapts itself to the environment and runs at maximum performance.

In some situations, you may need some of the following options to achieve optimum performance:

- by default, ATAPI devices are initialized to PIO mode only. If you intend to run particular ATAPI devices using busmaster DMA, apply the proper /A:x /U:y /BM options.

For a detailed discussion of all parameters see the Danis506.doc delivered with the driver.

NOTE By Daniela Engert: DaniS506.ADD v1.3.9b or later has both the "official" and the "inofficial" fix for the VIA686B bug. The official fix is applied automatically if the driver detects the affected chip revisions, the inofficial fix needs to be enabled by an undocumented option. This fix seems to be necessary even if you don't run any IDE hardware

Undocumented and unsupported ! (so don't ask Daniela) Parameter. Use only at _your_ ! own risk:

  • /FIXES:2

unofficial VIA686B bugfix. Only needed if a NEC Zip-100 works extremly slow (in comparison to a Zip-100 from Iomega). It is possible that other things refuse to work.

  • /!SETMAX

don't use max. Disksize. DANIS506.ADD uses the full disksize by default. If you have an old/defunct BIOS, some hardisks have the option to reduce the reported size. Together with this Parameter you can use this option. You can re-program the 'faked' size by using an actual DISKINFO.EXE.

  • /PROT0

(PROT-NULL!) writeprotect Track 0. Prohibits the 'killing' of alternative Bootmanagers by FDSIK/LVM. You can en-/disable the write protection with an actual DISKINFO.EXE

Installs support for diskette drives. Use this driver for PCs with PCI or ISA bussystems. See the Tips and Tricks section for more information. Supports diskette drives on non-Micro Channel PC's. 

BASEDEV=IBM1FLPY.ADD <parameters>

TIP: If you wish to prevent users from using the floppy drives under OS/2 (to keep them from loading non-authorised programs or in a workstation situation), REM the BASEDEV=IBMxFLPY.ADD line (where x is 1 for ISA and EISA machines, or 2 for Microchannel).

NOTE: In Warp, the install program may have placed both IBM1FLPY.ADD and IBM2FLPY.ADD BASEDEV drivers in your config.sys. Remove IBM2FLPY.ADD if you don't have a Micro Channel PC.

The correct setting for e.g. a IBM Thinkpad 560 with external floppy disk is (see the Warp Reference book for a detailed description): 

BASEDEV=IBM1FLPY.ADD /A:0 /FORCE:2 /U:0 /F:1.44MB /U:1 /F:1.44MB

Using the /DAPM Parameter (which disables the Power Managment) may also help on some Notebooks (e.g. Thinkpad 600) who can't find the Floppy.

IBM1S506.ADD

Installs support for IDE drives. Use this driver for PCs with PCI or ISA bussystems. See the Tips and Tricks section for more information. It supports busmastering only on Intel chipsets, if you have a none Intel chipset I recommend to use the Danis506.add driver. The OS/2 IDE Controller Adapter Device Driver (IBM1S506.ADD) for Non-Mcro Channel PC's.

Supports the following chipsets: CMD640, RZ1000, I82371FB,PIIX3,ORIO, PIIX4,I82801AA, I82801AB, I82801BA, CMD646, CMD648,VIA586B,VIA596B, VIA686A,SIS630

Intel chipsets restrictions: In case there are 2 devices on a channel on any Intel 82801 chip, the top UDMA mode will be limited to UDMA 2.

VIA chipsets restrictions: All of the chipsets have a problem with 40 pin cable detection. to ensure the proper operation, please check what kind of IDE cables are used. If you have a 40 pin cable on any channel, please specify the parameter /UDMA:2 in CONFIG.SYS . Any VIA chipset, which is not in the list above, but has the same Device ID, will be detected as VIA586B and performance will be dropped down to UDMA 2.

SiS chipsets restrictions: Since there is a problem for these IDE contrllers to work in UDMA mode with the secondary channel when 40 pin cable is installed, the driver will drop to PIO mode on this channel if 40 pin cable is detected. This, however, does not apply to primary channel. It is not advised to use /UDMA:x parameter on SiS IDE controllers. 

BASEDEV=IBM1S506.ADD <parameters>

Parameters A list of all parameters is enclosed in your OS/2 online help. New Parameters (not listed in online help):

  • /W

(Wait) pauses the config.sys after displaying the verbose

  • /!SHUTDOWN

disables the new shutdown behaviour.

  • /FORCE

Forces the emulation of an IDE CDROM drive, even though one is not present.

  • /UDMA:x

Limits the highest UDMA mode, x can be from 1-9.

  • /!UDMA

Disables UDMA

  • /!BIGLBA

disables 48bit LBA support and reverst to legacy 28bit LBA (in this case max. disk size is 137GB)

  • /CDA

Enables chipset extended detection algorithm for Intel chipsets.

If you are using the /BM or !BM parameters to enable or disable busmaster; you MUST specify the adapter with /A:x. You can also specify the unit on that adapter with /U:z. For example: 

BASEDEV=IBM1S506.ADD /A:0 /U:0 /!BM or /A:0 /!BM to disable BUS Master DMA

BASEDEV=IBM1S506.ADD /A:0 /U:0 /BM or /A:0 /BM to enable

TIP: If you have an IBM Thinkpad 760E/ED/ELD/EL that exhibits sluggish harddisk behaviour (pausing intermittently with hard drive light on) after FixPaks have been applied, add the /!BM parameter to the BASEDEV=IBM1S506.ADD statement (if present) in your CONFIG.SYS. This will disable the Bus Mastering function whose default has been changed from OFF to ON. Example: BASEDEV=IBM1S506.ADD /A:0 /!BM /U:1 /ATAPI /FORCE

TIP: A 'New Feature' that went into IBM1S506.ADD to flush buffers more reliably during shutdown using C-A-D seems to cause some disks to SPIN DOWN and stay there. Add " /!SHUTDOWN". This is known to fix the problem.

NOTE: /SMS! works only if the hardware doesn't report SMS capability, otherwise SMS enabled will be used regardless if the parameter is set or not.

BASEDEV=IBM2SS14.SYS

ATTENTION: Must be in front of all other PCMCIA Drivers, but after PCMCIA.SYS

Parameter:

  • /C0=z

These parameters define the IRQ level to be used by the

  • /C1=z

Socket Services driver. The new Card Services and Socket Services drivers for OS/2 do not use a hardware interrupt to notify the PCMCIA status change, so you do not need these parameters.

  • /IG0=y

This parameter defines a slot number, which Socket Services ignores. If you use the "Point enabler" supplied with a PC Card, you should take into consideration the coexistence with Socket Services.

For Example, "/IG0=1" defines that slot 1 is reserved for a "Point enabler" and Socket Services will ignore the slot.

  • /RI0=x

This parameter defines a slot number, where Socket Services disables the RI_OUT signal. If you are using a modem card with a ThinkPad computer, and you can't enable the "suspend" or "hibernation" function while the modem card is inserted, please try this parameter.

For Example, "/RI0=1" specifies slot 1.

  • /D

This parameter enables "Warm docking" from the view point of PCMCIA hardware. By adding this parameter, two additional PCMCIA slots are reserved for the docking station.

  • /APOFF

This parameter turns off the Auto-Power Mode. If the Auto-Power Mode is ON, a PC Card will be automatically turned ON by the hardware when it is inserted. The default for Auto-Power Mode is ON.

  • /IO0=s

This parameter defines the slot number, for which Socket Services will change the way the -IOCS16 signal is generated. By default, the -IOCS16 signal is generated based on the -IOIS16 signal from the PC Card. If this parameter is specified, the -IOCS16 signal is generated based on the I/O data size which is specified by the Client program. This option is needed for some cards which do not generate the -IOIS16 signal. You need to verify this information with PCMCIA card vendors.

For Example, "/IO0=1" specifies that the -IOCS16 signal for slot 1 is to be generated based on the I/O data size specified by the Client program.

Point Enabler Adapter card drivers are device drivers that support specific Adapter cards without requiring the use of the Card and Socket services provided in the PC Card Director package.

Problems using these Point Enabler device driver will occur when used in conjunction with the Card and Socket Services. The problem that must likely will occur is that the Point Enabler Adapter card will not function. The PC Card Director will indicate that the Card Type is incorrect and the Status of the Card will be 'IN' instead of 'READY'.

In order to use a Adapter card with Point Enabler Device driver a configuration parameter must be added to the IBM2SS14.SYS device driver entry in CONFIG.SYS. The parameter is as follows:

  • /IG0=y

Where 'y' defines the slot number that contains the Adapter card using the Point Enabler Device Driver.

After the system has been rebooted the slot specified in the configuration parameter will be ignored by Card and Socket Services allowing that slot to be used by Point Enabler device drivers. It also means the following:

- the PC Card Director program will not detect the insertion or removal of adapter cards in that slot - Adapter cards with device drivers that utilitize Card and Socket Services can no longer use that slot

The following is a list of Adapter Cards that use Point Enabled Device Drivers:

  • IBM 10/100 EtherJet Cardbus Adapter
  • IBM 10/100 EtherJet Cardbus Adapter with 56K modem
  • Intel PRO/100 Cardbus II
  • Xircom CreditCard Ethernet Adapter II

IBMATAPI.FLT

Filter driver ATAPI disks. New with Fixpaks since Fixpak 6/35 supports ATAPI Removable Media like ZIP100 and ZIP250, LS120 attached to an IDE Port. Since build 10.085 IBMATAPI.FLT is a superset of IBMIDECD.FLT. So make sure IBMIDECD.FLT is not in your config.sys.

TIP: If you have removable media drives (MO, IOMEGA, SYQUEST and others) look at http://rheooptik.fmf.uni-freiburg.de/www/faq/ remmedia.htm for a detailed removable media FAQ. 

BASEDEV=Ibmatapi.flt

PARAMETER (since 10.085)

  • /V

Verbose Mode, displays filter status on detected and emulated devices.

  • /A:n

Specify adapter: 0 = primary, 1 = secondary, 2 = DockingStation primary, 3 = DockingStation secondary.

  • /I

Ignore adapter n specified by /A:n. Example: "/A:1 /I" secondary IDE channel will not be filtered.

  • /U:n

Specify unit: 0=master, 1=slave.

  • /!U:n

Specified unit will be ignored. Examples: "/A:1 /!U:1" ignore(not claim) slave unit on secondary IDE channel. "/A:2 /!U:0" ignore(not claim) DockingStation UltraBay.

  • /SCSI

Export IDE device as SCSI device. Can be used to emulate SCSI CD-RW device as IDE CD-RW device. Example: "/A:1 /U:0 /SCSI" will report SCSI CD device attached as secondary IDE channel master unit .

  • /TYPES:xxx

Specify device types supported by WarmSwap. x can be C=CD (CD-ROM,CD-R, CD-RW, DVD, etc), L=LS (LS-120, LS-240), Z=ZIP. Examples: "/A:1 /U:0 /TYPES:CLZ" enable swapping between CD, LS and ZIP "/A:1 /U:0 /TYPES:CZ" enable swapping only between CD and ZIP If certain device is in the UltraBay during Boot it will be enabled for swapping. /C IBMATAPI.FLT has been modified so that it no longer fills the request's S/G list with 0's for the commands without data transfer phase, even if the particular command contains a valid S/G list. To avoid possible unforeseen compatibility problems with older drivers, /C parameter disables this new behavior.

IBMIDECD.FLT

This filter driver makes your IDE CDRom drive visible to OS/2. Support for ATAPI CD-ROM drives attached to an IDE Port. Superceded by IBMATAPI.FLT V 10.085. It is important to use IBMIDECD.FLT with the IBM1S506.ADD driver. Since Ver. 10.047 IDE CD-Writers for reading/writing are supported. Note: To get CDRom support in OS/2 you must also install IBM1S506.ADD and Os2cdrom.dmd . 

BASEDEV=IBMIDECD.FLT <parameter>

Parameters:

  • /V

Displays some information during the boot.

  • /C

IBMATAPI.FLT and IBMIDECD.FLT have been modified so that they no longer fill the request's S/G list with 0's for the commands without data tranfer phase, even if the particular command contains a valid S/G list. To avoid possible unforseen compatibility problems with older drivers, /C parameter disables this new behavior.

IBMKBD.SYS

Provides support for your keyboard. Some Tools e.g. the Ctrl-Alt-Del Commander form Perez Computing or the Process Commander from Stardock are replacing KBDBASE.SYS by there own version. Whenever you deinstall these tools manually be sure to revert to the original KBDBASE.SYS. It is also reported that Process-Commander fails with Warp 4.5 versions (WSeB and Warp4 Fixpak 13 or higher) 

BASEDEV=IBMKBD.SYS <parameters>

Parameter:

  • /NONE

Assumes a keyboard is installed even if a keyboard is not attached. Starts OS/2 even when no keyboard is attached. Useful for unsupervised operation.

  • /NUMON

Turns the numeric keys on your keyboard on. This switch works only on some configuratins, it depends on what a keyboard you have and what Codepage you use.

  • /NUMOFF

Turns the numeric keys on your keyboard off.

TIP: For the mostly sold so called 'Win95-Keyboards' (how ironic, as with windows9x you can only loose) there are two replacement drivers: One by Robert Muchsel (muchsel@acm.org), Release is Ver 2.00 available under winkey02.zip, and a newer one available at: http://os2.avi.kiev.ua/ Release is ver.021

TIP: By Kovacs Istvan: If you try BASEDEV=IMBKBD.SYS /NUMON numlock could turned on like with the utility 'jshifter'. Works only with some releases of the IBMKBD.SYS delivered with Warp. According to the mails I've got it seems that the parameter doesn't work on nearly most keyboards, (but one some) so you have still to use 'jshifter' available at: http://www.gbar.dtu.dk/~c948129, or 'numlock' by Peter Engels available at http://www.uni-bonn.de/~uzs0ad.

TIP: If you prefer a so called Dvorak keyboard layout (a keyboard which tends to arrange the characters more ergonomic than the qwerty type - which was a need when constructing mechanical typewriters at the end of the 19.th century - since Fixpak 8 for Warp 4 (maybe earlier, but this was the first time I was aware of its existance) go to your keyboard settings in the System Setup folder and simply select Dvorak (for left and righthanded !, but only in English). Now you only need a keyboard with a Dvorak layout (or one of these old but beautiful IBM keyboards with a 'klick' and 'solid as a rock', here you can pull the caps and place em where you want). This is another new goodie in OS/2 IBM never speaks of.

PPAOS2.ADD

Parallel Port-attached ZIP 100, ZIP+, and ZIP 250 driver

This driver supports daisy chaining, up to a total of five drives. The connections must be CPU -> ZIP Plus/250 -> ZIP Plus/250-> ZIP (original), which MUST be last. Note that ZIP Plus terminator MUST BE OFF unless it is the LAST drive in the chain. If a ZIP (original) is the last drive, then the ZIP Plus termintor MUST BE OFF. 

BASEDEV=PPAOS2.ADD

Parameters

  • /V Verbose Output
  • /PORT:# # = Parallel port address (ie 378, 278, 3bc)

MULTIPLE PARALLEL PORT DRIVES Each driver instance supports ONLY one parallel port. To install TWO instances, you MUST specify the /PORT: parameter on at least one driver statement to get to the LPT2 port; for example: 

 basedev=ppaos2.add /port:378
 basedev=ppaos2.add /port:278

LIMITATIONS OS/2 versions that use LVM for managing hard file space exhibit several pecularities working with ZIP drives.

  1. Even though media is inserted at boot time, a drive letter may not be assigned. To force the assignment of a driver letter, double click on the "Refresh Removable Media" object. If that fails, eject the media, re-insert, and double click on the "Refresh Removable Media" object.
  1. LVM may report the ZIP drive as corrupted. You can still create a volume.
  1. Do NOT do an LVM "Commit Changes" with ZIP media that already contains data inserted. The data may be lost.

PRINT01.SYS

Provides support for your parallel ports LPT1, LPT2 and LPT3 on PCs with ISA or PCI buses. 

BASEDEV=PRINT01.SYS <parameter>

WARP TIP: With Warp, the default transmission protocol used by PRINTO1.SYS and PRINTO2.SYS is the polling transmission method. The protocol used by previous versions of OS/2 was the interrupt transmission method. In Warp, you can change back to the interrupt method by adding the /IRQ parameter.

TIP: From Paul Kurr: "Since I'm running on a LAN at work here, I have no need for direct printer support of any kind since this is taken care of by my NOS (LAN Server). So I have REM'd BASEVEV=PRINT01.SYS to save some RAM."

Beginning with V. 10.049 PCI Add-On Cards are supported and beginning with 10.068 Combo Cards.

Parameter:

  • /IRQ

This parameter change the transmission method from polling to interrupt. The interrupt method is faster but won't work on every system. The used IRQ depends on the I/O address the LPT-port uses. IRQ 5 is used on LPT ports installed on the I/O address 278, IRQ 7 is used on LPT ports installed on the I/O address 378 or 3BC. To find out the I/O address of a LPT port use the Hardware-Manager.

  • /SHR

This parameter in conjunction with /IRQ parameter directs the PP DD to service PCI IRQs as shared.

NOTE: If your printer (for example, old dot matrix printer) generates IRQs without setting interrupt pending (occured) bit in PCI PP status register correctly then you cannot use PCI IRQ sharing and must not use /SHR parameter.

  • /TOU:ddd

Specifies maximum wait time in seconds before canceling the print request. This is a 3 decimal digit value (by default - 120 seconds).

  • /F

Find PPs on PCI combo (serial/parallel) cards automatically.

  • /MPL

modifies polling procedure - makes it less processor resource consuming by scheduling other systems tasks at certain print points, may decrease print speed.

BASEDEV=PRINT02.SYS parameter

Parameter:

PC Card

PCM2ATA.ADD

Driver for PCMCIA harddisk drives. 

BASEDEV=PCM2ATA.ADD <parameters>

Parameters.

  • /S:n

Specifies the number of PC Card slots. /S:1 shows that there is only one PC Card slot. When this parameter is not set, the number of PC Card slots is set to 2.

  • /P:hhhh

Specifies the lower limit for the I/O address of the ATA card. The device driver assigns the next usable I/O address from this lower limit to the card. When this parameter is not set, the device driver looks for a usable address and assigns it to the card.

  • /EXIRQ:n

Specifies the IRQ level that is not assigned to the card. You can set more than one IRQ level.

  • /NOBEEP

Specifies not to beep when a storage card is installed. When this parameter is not set, you will hear a beep every time a storage card is installed into the PC Card slot.

  • /B

Specifies that OS/2 has started from an ATA card. When this parameter is set, there will be no redundancy in assigning the logical drive to the slot where OS/2 was booted. It depends on the ATA card whether you can start OS/2 from it.

  • /STBTIME:n

Specifies the time (from 1 to 21 minutes) until entering standby mode. When the ATA card is not accessed for the time specified by this parameter, the ATA card enters standby mode (only when your ATA card supports standby mode). When this parameter is not specified, standby mode for the ATA card is disabled.

  • /MDRV:n

Specifies the number of extra drives that can be used in addition to the number of PC Card slots available for the PCMCIA storage devices. When this parameter is not specified, no extra drive is given to the device driver. The extra drives can be activated by the PCMCIA ATA Card Mount utility.

  • /!DM

Specifies not to use OS2DASD.DMD as the device manager. When this parameter is set, OS2PCARD.DMD is used instead.

Example:

PCMCIA.SYS

Base support for PCMCIA cards. 

BASEDEV=PCMCIA.SYS <parameter>

ATTENTION: Must be in front of all other PCMCIA Drivers

Parameter:

  • /R:200

Specify that card services will conform to the PCMCIA 2.0 standard. This is the default value.

  • /R:500

Specify that card services will conform to the PCMCIA 5.0 standard instead of the PCMCIA 2.0 standard which is the default value.

  • /P

In previous releases, this parameter disabled the hardware interrupt which was used by OS/2 Socket Services drivers to notify clients of a change in status. Neither the new Card Services nor Socket Services drivers for OS/2 use a hardware interrupt to signal PCMCIA status changes. So this parameter is no longer needed.

Installing PCMCIA

Unpack the file PCMCIADD found on disk 17 of the OS/2 Warp install CD (directory OS2IMAGE), best into the OS2 directory on your harddisk. Then replace the line BASEDEV=IBM2TOS1.SYS with the following lines in your CONFIG.SYS: 

BASEDEV=IBM2AMB1.SYS
BASEDEV=IBM2AST1.SYS
BASEDEV=IBM2CAD1.SYS
BASEDEV=IBM2CMQ1.SYS
BASEDEV=IBM2MAT1.SYS
BASEDEV=IBM2NCR1.SYS
BASEDEV=IBM2NEC1.SYS
BASEDEV=IBM2SS01.SYS
BASEDEV=IBM2SS02.SYS
BASEDEV=IBM2TOS1.SYS
BASEDEV=IBM2ZEN1.SYS
BASEDEV=IBM2ZOS1.SYS
BASEDEV=SS2PCIC1.SYS
BASEDEV=SS2TCIC1.SYS

When OS/2 boots press Alt-F2 when the rectangle appears in the top left corner of the screen, and OS/2 will tell you which driver was loaded. It is possible that your machine works with more than one, you'll then have to find out yourself which one works best!

If you have specific drivers for your notebook computer

Do not install the PCMCIA support when installing OS/2 on your machine. Instead, once you are done with the installation of OS/2, chose Device Installation from the System/System Configuration folder and install the PCMCIA driver from diskette or use the installation program provided with your driver. Check the information provided with your driver before installing OS/2 Warp or the PCMCIA support.

If your driver comes only in the form of the driver files, you need to do a manual installation, i.e. you need to edit the CONFIG.SYS file yourself. In that case install any PCMCIA support (as explained above). Then copy the driver files into the directory x:\os2\boot. After that, open the CONFIG.SYS in the editor and change the line BASEDEV= PCMCIA_driver (replace "PCMCIA_driver" with the driver name you installed) into BASEDEV=newdriver where "newdriver" is the name of the driver file you got). Take care that the PCMCIA drivers precede any COM drivers.

In some machines, an additional line has to be included in the CONFIG.SYS file: BASEDEV=RESERVE.SYS /mem:nnnn mmmm (nnnn has to be replaced with the address where PCMCIA usually would start and mmmm has to be replaced with a value of 1000 or more (increased in steps of 1000)). First run rmview /mem to find out at which address PCMCIA is located. This would be the hex number that comes in place of nnnn. Then try out whether it works with 1000 (in place of mmmm). RESERVE.SYS actually prohibits the PCMCIA driver to use this area and thus avoids a conflict which otherwise arises. If 1000 doesn't work try 2000 etc.

Xircom's own drivers don't work: For some PCMCIA cards (particularly XIRCOM with their own drivers) the IBM PCMCIA socket for the particular socket in which the card is inserted has to be disabled by installing socket services with the parameter /S0=1 which will disable socket services for the second PCMCIA slot (if there are two slots; if there is just one slot it won't do any good). An alternative is the switch /ig0=1 (1 is the port number). By using a proper script, it may even be possible to go without any of these switches.

PCMCIA doesn't work: In some notebook computers the BIOS has to be modified so that the PCMCIA becomes compatible with the available OS/2 driver. The mode in which the PCMCIA functions may need to be set from Busmaster to 16-bit or PCIC compatible. Check the info for individual notebooks on this page and consult your notebook's manual!

IBM Token Ring PCMCIA adapter doesn't work: Try setting in MPTS the IRQ to 5 and the adapter type from primary to alternate (address X=20).

RESERVE.SYS

This driver reserves hardware ressources for drivers, especially for those who are not recognised by the ressourcemanager. 

BASEDEV=RESERVE.SYS <parameters>

See OS/2 Reference Book for a detailed discussion of the parameters.

Tip: By Sam Detweiler: "for adapters that are not PnP and do not have a legacy detector, one can use the DOCUMENTED approach of adding a BASEDEV=RESERVE.SYS /p:2e8,8 to the config.sys and re-running hardware detection at the next boot. It causes the reserve.snp to preallocate the defined resources so that PnP adapters can't use them.

Tip: By Paul F.Grobler: The tablet / enhanced mouse driver by M. Finney was broken by the GA code of Merlin but I found a workaround. The symptoms I got was an error free driver load (including vmouse.sys), a mouse cursor on the first graphic mode screen but the mouse pointer was static i.e. it would not move. All that was required was to put a "BASEDEV=RESERVE.SYS /IO:3f8,8 /IRQ:4" as the first line of my config. sys. You will note that the values correspond to normal com1 as this is were my tablet is connected. By modifying the values to /IO:2f8,8 and /IRQ:3 this should work for com2.

Tip: All cards are memory: In some machines, an additional line has to be included in the CONFIG.SYS file: BASEDEV=RESERVE.SYS /mem:nnnn mmmm (nnnn has to be replaced with the address where PCMCIA usually would start and mmmm has to be replaced with a value of 1000 or more (increased in steps of 1000)). This line should be at the beginning of the CONFIG.SYS file. First run rmview /mem to find out at which address PCMCIA is located. This would be the hex number that comes in place of nnnn. Then try out whether it works with 1000 (in place of mmmm). RESERVE.SYS actually prohibits the PCMCIA driver to use this area and thus avoids a conflict which otherwise arises. If 1000 doesn't work try 2000 etc.

STARTUP.SYS

VIA 8233 Startup Sound driver. 

BASEDEV=STARTUP.SYS <parameters>

An AC'97 adaptation of the famous "SoundBlaster Startup Sound Driver" by Robert Muchsel. All the driver does is randomly playing a short tune during OS/2 startup (then it uninstalls itself, hence consuming no memory).

Besides serving as an amusement, the driver may also be useful in locating IRQ sharing problems - if the MMPM/2 driver, VIAUDD.SYS, does not work while STARTUP.SYS does, the IRQs should be examined for conflicts.

The driver requires a 14.xxx kernel.

Parameters:

  • /MV:

Set master volume to n% (0 to 100). Default is /M:100.

  • /V:

Set output volume to n% (0 to 100). Default is /V:100.

  • /SV:

Set PC Speaker volume to n% (0 to 100). Default is /SV:60.

TI11225CB.SYS

Socket Services driver for Dell Latitude CpiA 

BASEDEV=TI11225CB.SYS

Parameter:

  • /C0=z

These parameters define the IRQ level to be used by the

  • /C1=z

Socket Services driver. The new Card Services and Socket Services drivers for OS/2 do not use a hardware interrupt to notify the PCMCIA status change, so you do not need these parameters.

  • /IG0=y

This parameter defines a slot number, which Socket Services ignores. If you use the "Point enabler" supplied with a PC Card, you should take into consideration the coexistence with Socket Services.

  • /RI0=x

This parameter defines a slot number, where Socket Services disables the RI_OUT signal. For Example, "/RI0=1" specifies slot 1.

  • /D

This parameter enables "Warm docking" from the view point of PCMCIA hardware. By adding this parameter, two additional PCMCIA slots are reserved for the docking station.

  • /APOFF

This parameter turns off the Auto-Power Mode. If the Auto-Power Mode is ON, a PC Card will be automatically turned ON by the hardware when it is inserted. The default for Auto-Power Mode is ON.

  • /IO0=s

This parameter defines the slot number, for which Socket Services will change the way the -IOCS16 signal is generated. By default, the -IOCS16 signal is generated based on the -IOIS16 signal from the PC Card. If this parameter is specified, the -IOCS16 signal is generated based on the I/O data size which is specified by the Client program. This option is needed for some cards which do not generate the -IOIS16 signal. You need to verify this information with PCMCIA card vendors.

USB

USBUHCD.SYS

Driver for the USB port controller. You need also Usbd.sys and Usbhid.sys installed. For now only UHCI compatible USB controllers are supported. These are only the chip sets from Intel and VIA. 

BASEDEV=USBUDCD.SYS <parameter>

TIP: If you use the version from the Device Driver Pak2 available at: ftp://service.boulder.ibm.com/ps/products/os2/fixes/DDPak/xr_d002 the drivers supports Intel and VIA chipsets.

NOTE: On IBM 365 System you have to add the parameter /FS

TIP: A lot of Athlon motherboards are using the Via Southbridge VT82C686A chipset which provides 4 USB ports. Do you know if the Via drivers work with this Via chipset?". Robert Lalla, the author of the patched USB driver that works with VIA chipsets replied with this tip on how to get IBM's latest USB driver to work with VIA chipsets by applying a patch:

The VIA version of UHCI host driver that I uploaded to Hobbes last October is working for mice, keyboards, hubs and modem peripherals, maybe audio. For printers and removable disks updated USB base drivers are recommended. They are supplied from IBM together with the USB printer drivers. But again this USBUHCD.SYS is only enabled for Intel. The following patch script will add VIA support to USBUHCD.SYS dated Jan 2000: 

-----save as VIA.PAT---------
FILE USBUHCD.SYS
VER 2F2B C747040300
CHA 2F2E 01
------------------------------
  1. copy VIA.PAT to \OS2\BOOT
  2. set current directory \OS2\BOOT
  3. create a backup copy of USBUHCD.SYS
  4. run: PATCH VIA.PAT /A

A special aspect of the 686a Southbridge is that it does not contain one USB controller having 4 ports but instead 2 controllers (2 ports each). So unless one of both controllers is disabled explicitly, USBUHCD.SYS should be loaded twice(!) in CONFIG.SYS.

Parameter:

  • /V

Verbose Mode, displays driver information during OS/2 initialization.

  • /FS

Forces driver to stop USB host during OS/2 shutdown process. This parameter can be used to prevent POST (power on system test) failure on some hardware with legacy keyboard.

Tested UHCI Adapters or Controllers
  • D-Link DU-A2 PCI USB controller

ATAPIMO.FLT

MO device filter from Fujitsu 

BASEDEV=ATAPIMO.FLT

NOTE This driver is fully substituted by the DANIATPI.FLT

Parameters
  • /Rn or /R:n

(Number of reserved drives) 'n' is a number between 1 and 10. Default is 1. A series of logical drive names can be reserved for each MO drive for future partitioning. If the number of valid partitions exceeds the number specified /R option, and if /S option is not specified, up to 16 partitions are allowed.

  • /S

(Reserved drive priority) No more logical drives than the number of /R option is assigned. When the number of reserved drives specified with the /R option is fewer than the number of valid partitions on a disk, the number of reserved drives takes priority. For example, if there are four valid partitions on the disk and the number of reserved drives is specified at 3, a logical drive name cannot be assigned to the fourth partition, and hence it cannot be accessed.

  • /I {h:} m {[n]} {+-{h:} m {[n]}}+-...

(Specify the drive ID) This parameter specifies the target MO drive by the host adapter number and SCSI-ID number. If this option is not used, all accessible MO drives are used by default. h is the host adapter number (between 0 and 9). The default is 0. m is the SCSI-ID number (0 to 7). n is the number of reserved drives. When 'n' is omitted, the value specified with the /R option is used.

  • /U:{IDE adapter name}

(Required, specify IDE adapter driver) This parameter is not optional but required both for ATAPIMO.FLT and MODISK.DMD. You must specify same name for these two drivers. Usually '/U:ST506_HardDrive' works fine if 'IBM1S506.ADD' or 'IBM2S506.ADD' is used as IDE adapter driver.

DANIATAPI.FLT

This highly recommended filter driver by Daniela Engert (dani@ngrt.de) supports all types of ATAPI devices. It is a superset of IBMIDECD.FLT, IBMATAPI.FLT and DaniADsk.FLT, and supports all devices that the mentioned drivers do. Additionally, all ATAPI devices can be accessed through the OS/2 ASPI software interface. Each EIDE channel shows up as a SCSI channel, and each ATAPI device as a SCSI device (master = SCSI ID 0, slave = SCSI ID 1).

NOTE: Make sure that all other ATAPI related drivers are inactive or come after DaniATAPI.FLT in your CONFIG.SYS. If you intend to run the BootOS utility or to install this filter driver on a 8.3-only filesystem, rename the driver to DaniATAP.FLT.

  • can deal with the ATAPI ZIP-250
  • improved ZIP performance (up to factor 4 on ZIP-250)
  • supports arbitrary swapping of 100MB and 250MB media
  • reflects the current media capacity up to FDISK, DISKIO or the like
  • OS/2 boot from ZIP is possible
  • faster 32bit PIO in conjunction with DANIS506.ADD (rel. 1.1.1 or later)
  • Busmaster DMA mode works and is tested with Intel, VIA, AMD, HPT, SiS and CMD chipsets until now. Busmaster DMA is available now for ALi as well (CD/DVD-ROM is safe, but some chip revisions fail on DMA write operations!). Due to hardware limitations there is no 32bit PIO and no busmaster DMA possible for ATAPI devices attached to a Promise Ultra controller.
  • ATAPI devices appear to the rest of the system as regular SCSI-2 devices if used with DANIS506.ADD (rel. 1.1.5 or later). This may be disabled globally or individually.
  • advanced "hot-swap" support if used with DANIS506.ADD (rel. 1.1.9 or later)
  • support for PCCard (formerly: PCMCIA) ATAPI devices (like the Iomega PCMCIA ZIP-250 or the Iomega Click!40)
  • the translation of old-style 6-byte SCSI commands into their more modern 10-byte counterparts is no longer hardcoded. The device is sensed now to check if it requires this translation.
  • like DaniS506.ADD, this driver stores boot messages internally for later readout. To view them, issue "copy ATAPI$ con:", to dump them into a file, issue "copy ATAPI$ anyfile".
  • automatic media unload on shutdown if desired
  • supports up to eight IDE channels
BASEDEV=DANIATAPI.FLT

Parameter: This driver supports all switches and options that IBM1ATAPI.FLT supports.

Generic options

  • /!V

(quiet) (not) Verbose mode

  • /EJ

(don't eject) eject medium at shutdown

  • /ZA

(default mapping) map ZIP drive to A:

  • /!SCSI

(export all) don't export any ATAPI devices as SCSI devices

Adapter options

  • /A:n (n/a) Adapter number (0, 1, 2, 3)
  • /I (off) Ignore adapter
  • /EJ (don't eject) eject medium at shutdown
  • /!SCSI (export all) (don't) export ATAPI devices as SCSI devices

Unit options

  • /U:n - (n/a) Unit number (0, 1)
  • /UNIT:n - same as /U

  • /EJ - (don't eject) eject medium at shutdown
  • /!SCSI - (export) (don't) export ATAPI devices as SCSI devices
  • /RSJ - (off) RSJ CDROM backdoor. Installs an additional backdoor to re-enable regular CD ROM operation via OS2CDROM.DMD (or replacements).
  • /TYPE: - Units marked as "hot-swappable" on DANIS506.ADD's command line (by /FORCE /ATAPI) need the new option /TYPE: to advice DaniATAPI.FLT to report appropriate device types to the device managers. The same applies to PCCard adapter channels (marked as /FORCE /PCMCIA on DANIS506.ADD's command line). This is done by additional characters designating the supported device types:
  1. 'c' or 'C': all CD-ROM like devices (CD-ROM, CD-R/W, DVD-ROM, DVD-RAM)
  2. 'z' or 'Z': all ZIP drives
  3. 'l' or 'L': the LS-120 drive

  • /SHARE - allocates a device only while sending a command.
  • /ALL - no devices are allocated.

TIP: If you are using RSJ CD Writer 2.59 or above you may add the parameter /ALL to BASEDEV=OS2ASPI.DMD. Also needed by SANE and CDRECORD. After booting your machine, the recorder will be useable as a standard CDROM drive, and you will nevertheless be able to attach the CD to our filesystem. But please ensure that you're not using the CDROM drive letter at the same time when the CDR is attached to RSJ's filesystem, otherwise this will result in errors. If you are using RSJ CD Writer 2.7 you can add unsupported drives
