CONFIG.SYS - CALL Statements

Return to The Config.sys Documentation Project Main Page

The Call statement in your config.sys file is used to run a program during the boot up. Programs started by Call are executed in the foreground, the boot stops until the program has finished.

CALL=ATTRIB.EXE

Removes the read-only and systen attributes of the *.ini files

  CALL=drive:\OS2\ATTRIB.EXE -R -S -H C:\OS2\OS2*

See also CALL XCOPY

Platform Support:

OS/2 2.x	OS/2 3.0	OS/2 4.0	OS/2 4.5x	eCS 1.x	eCs 2.x
Yes	Yes	Yes	Yes	Yes	Yes

CALL=CACHEF32.EXE

It is a helper program needed by the Fat32.ifs file system driver. The program has several functions. It should be started from the config.sys file, but can also be executed from the command line.

 CALL=C:\OS2\FS\Fat32\CACHEF32.EXE <parameter>

Parameters:

• /?

Shows help to the parameter useage.

• /Q

Quits Cachef32.exe. Files in the cache are written to the disk.

• /N

Starts Cachef32.exe without the lazywrite daemon.

• /D:value

This is the amount of time that the disk had to be idle before data can be written from cache to disk. Value can be in the range from 0 to 65535 . Default= 1000 The value is expressed in milliseconds.

• /B:value

This is the amount of time that the cache-buffer had to be idle before the cache data must be written to disk. The OS/2 Online help says that the BUFFERIDLE time must be smaller than the DISKIDLE time. I think this is wrong! Value can be in the range from 0 to 65535 . Default= 500 The value is expressed in milliseconds.

• /M:value

This is the time data waits in the cache before the data is written to disk. Value can be in the range from 0 to 65535 . Default= 5000 The value is expressed in milliseconds.

• /R:Drive:,value

Sets the Read Ahead sectors for the the specified drive to the value.

• /L:value

Turns lazy write on or off. Value can be ON or OFF . Default = ON

• /FS

Use short names internally.

• /FL

Use long names internally. Please read the section about the long filenames in the FAT32 documentation.

• /P:value

Sets the priority for the lazy writer. Value can be in the range from 1 to 4 Default = 1 note: The /T options has been removed since version 0.83.

Platform Support:

Yes	Yes	Yes	Yes	Yes	Yes

CALL=CHKDSK.COM

This CALL statement will call the new 32-bit CHKDSK.COM, and will tell it what drive to check (e.g. C:). This CALL statement must appear after the LIBPATH=, SET PATH=, and SET DPATH= statements, but before any other CALL statements in your CONFIG.SYS file.

The /C option tells CHKDSK to check the drive only if it is "dirty" and it needs checking. It needs BASEDEV=CHKDSK.SYS loaded.

Platform Support:

OS/2 2.x	OS/2 3.0	OS/2 4.0	OS/2 4.5x	eCS 1.x	eCs 2.x
Yes	Yes	Yes	Yes	Yes	Yes

CALL=CMD.EXE

With this statement you can 'delay' the initialisation of the presentation manager. The effect is the same as if you would press 'ALT F1' during boot (as long 'OS/2' is visible on the left upper corner of the display) and then selecting the command-line option (F2 in Warp4). After typing 'exit' the command-line will be closed and boot-up finishes. Useful if you have to delete locked files (specially locked dll's).

  CALL=drive:\OS2\CMD.EXE

For starting another instance of the command processor and executing programs

See RUN CACHE386.EXE and CALL MPTSTART.CMD

Platform Support:

OS/2 2.x	OS/2 3.0	OS/2 4.0	OS/2 4.5x	eCS 1.x	eCs 2.x
Yes	Yes	Yes	Yes	Yes	Yes

CALL=Dcf2.exe

This driver is used by the DCF/2 disk compression program.

CALL=C:\Dcf2\Dcf2.exe parameter 

Platform Support:

OS/2 2.x	OS/2 3.0	OS/2 4.0	OS/2 4.5x	eCS 1.x	eCs 2.x
Yes	Yes	Yes	Yes	Yes	Yes

CALL=NetBind.exe

This program binds the protocols to the adapter driver that the NDIS Protocol Manager ( Protman.os2 ) tells it to.

CALL=C:\Ibmcom\Protocol\Netbind.exe

note: This program has no parameters.

Platform Support:

OS/2 2.x	OS/2 3.0	OS/2 4.0	OS/2 4.5x	eCS 1.x	eCs 2.x
Yes	Yes	Yes	Yes	Yes	Yes

CALL=Svdc.exe

It is used by the Super Virtual Disk tool, which emulates a floppy or harddisk drive in memory.

CALL=C:\SVDisk\SVDC.exe parameters

OS/2 2.x	OS/2 3.0	OS/2 4.0	OS/2 4.5x	eCS 1.x	eCs 2.x
