- Software requirements:
-
- OS2 1.2 after internal release 12.134 for minimal functionality.
- OS2 1.21 after internal release 121.185 for CDROM required kernel
- fixes. This will give the most bug-free operation.
-
- Config.sys Parameters : May be any of the following.
-
- /k Instructs the FSD to first search for a secondary volume
- /K descriptor. If not found, the volume descriptors are
- then searched for a primary volume descriptor. This is
- used to read Kanji disks.
-
- /c:<#> Tells the FSD how many 64K segments to use for the sector
- /C:<#> cache. The default is 2, meaning 64 sectors are cached.
- This value must be between 1 and 65535. The actual number
- of cached sectors is this value times 32.
-
- /m:<#> Tells the FSD the maximum number of disk sectors to read at
- /M:<#> a time. The default is 8 (16K). The maximum is 31 sectors
- or 25% of the total sector cache, whichever is smaller.
-
- /quiet Suppresses any signon messages.
-
- The /c parameter must appear before the /m parameter or the /m
- parameter will be ignored and the default value used.
-
- Example : The following instructs the FSD to search for a secondary
- volume descriptor, cache 128 sectors and read a maximum
- of 20 sectors at a time. In this case the FSD is
- put in a directory named c:\ifs.
-
- ifs=c:\ifs\cdfs.ifs /k /c:4 /m:20
-
- The following can be used to read the primary volume
- descriptor use the default cache and read-ahead values.
-
- ifs=c:\ifs\cdfs.ifs
-
- The CDROM FSD swaps out the sector buffers into the swapfile on the
- harddisk. The value for the /C parameter is constrained by the swapfile
- not the physical memory of the machine.
-
-
- Put the dll, UCDFS.DLL in a directory on your libpath.
-
- This dll provides compatibility for the utility functions SYS,
- FORMAT, CHKDSK, and RECOVER. These are basically no-ops for CDROM
- except CHKDSK which returns the size of the CDROM volume.
