For introductory information about file systems, select from the following list:
Press "Optimize" to have &xwp; propose you new, optimized settings.Press "Default" to have the OS/2 default settings displayed on the notebook page.
By pressing "OK", the selections you made will be translated into the "Parameters" field on the "Drivers" page in the "OS/2 Kernel" settings notebook. This does not change your CONFIG.SYS yet. To do that, press "Apply" on the "Drivers" page after pressing "OK" in this dialog.
It is strongly recommended to enable Joliet support. This is Microsoft's extension of the ISO standard CD-ROM file system to support long file names (up to 64 characters) on CD-ROMs also. Many newer CD-ROMs are unreadable on OS/2 if this setting is not enabled.
I am unsure what Kanji support does. I guess it has something to do with the Japanese language?
The "cache size" slider sets the size of the CD-ROM file system cache. The default of 128 KB is not a whole lot, so it is recommended to set this to 512 KB or higher. Since the read head of a CD-ROM drive is a lot slower than those of a hard disk, a larger cache can really speed up CD-ROM reading.
For the same reason, you should set the "File sectors to read at a time"
to the maximum value. This setting determines how many sectors are read in when
a single sector is requested from the file-system driver. Since it is likely that
not only one sector, but the following sectors will also be read when a CD-ROM is
accessed, the following sectors will already be in the cache, which reduces physical
access to the CD-ROM also.
Finally, the settings in the "Initialization" group determine what the
IFS driver displays at startup. Per default, it will give a short message
that it has been loaded. "Quiet" will force it to display nothing, while
"Verbose" will have it display the current IFS settings, as specified
above.
