USB Mass Storage Driver for e.g. USB 1.44M Floppy Drive and Iomega 100/250MB portable USB ZIP drive. It works with USB flash drives and USB HDD.
BASEDEV=USBMSD.ADD /FLOPPIES:0 /REMOVABLES:n
- TIP
- By Daniela Engert: with BASEDEV=USBMSD.ADD /FIXED_DISK /FLOPPIES:0 /DEVICES:1 the USB Zip 100 should work.
- NOTE
- During boot USBMSD.ADD creates an empty list with the selected (default1) numbers of devices. Whenever you attach a device it will be connected to this list. This also means, if you attach more devices than specified in the list, they won't be recognized.
Parameter
- /V
- Verbose Mode, displays driver information during OS/2 initialization.
/BUFFER:n
- Sets transfer buffer size for LS and FS devices.
- /A_USAGE
- n
- Parameter controls usage of 'A' drive flag for the 1st floppy device. The following values of n can be used:
- 0 - 'A' drive flag is not used;
- 1 - 'A' drive flag is used;
- 2 (default value) - 'A' drive flag is used only if there is no other device driver using this flag.
/GPT:n
- Sets how many of the REMOVABLES are reserved for GPT disks.
- Default=0.
- /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.
- /REMOVABLE_AS_FLOPPY
/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.
/REMOVABLES:n
- Number of removable media devices to be served (by default 1). For example, the statement "BASEDEV=USBMSD.ADD /FLOPPIES:2 /REMOVABLES:3" serves 2 floppy devices (including LS-120 Super Disk devices), 3 removable media devices (like IOMEGAZIP drive). In order to remove service the key value must be set to 0.
- /REMOVABLE_AS_FLOPPY
- System uses removable disks as Large Floppies.
- /CHS
- Driver calculates and adds Cylinder/Heads/Sectors values to device geometry. This key helps to support USB drives with capacity more than 40GB for systems with os2dasd driver without 512GB support and for non-LVM systems.
- /MS10_OFF
- Driver avoids of using ModeSense10 command for geometry detection.
- /U
- Make unusable devices usable. Normally disks which are not MBR or wiped are marked unusable to prevent damaging them.
- This switch disables the check and makes all disks usable.
Additional debugging options:
- /BP
- Execute an int 3 breakpoint immediately upon parsing this switch.
- /W
- Causes the debug buffer to wrap. The default is nowrap.
/COM:<port>
- Causes debug messages to be output to the specified serial port.
- 1=0x3f8, 2=0x2f8, 0xnnnn specifies the COM port base address.
/BAUD:<baud>
- Sets the serial Port to the specified speed. Only valid if /COM is specified first.
