CDFS.IFS (CONFIG.SYS)
The CDFS.IFS enables support for CD-ROMs. Without this, you can't use your CDROM drive.
IFS=C:\OS2\BOOT\CDFS.IFS <parameters>
Default settings:
IFS=C:\OS2\BOOT\CDFS.IFS /C:2 /M:8
Parameters:
- /C:value
This sets the size of the cache. Value is expressed in blocks of 64 Kbytes.
- /M:value
This sets up the maximum number of file sectors read at the same time.
- /P:value
Defines the debug output port (COM1 or COM2). Value can be 1 or 2
- /K
Enables the volume descriptor by kanji.
- /Q
Disables error message at boot up.
- /V
Shows the used settings at boot up.
- /W
Enables support for the Joliet CD-ROM format. This parameter is new with Warp 3 fixpak 32 and Warp 4 fixpak 5. Currently not all versions of the Joliet CD-ROM format are supported.
Example To read the full name of files from a Joliet CD format you can add "/W" on the CDFS.IFS command on your config.sys: (It had to be Warp 4 with FP5 or higher)
