VDISK.SYS

As in DOS, this driver installs a RAM disk. In this example, the RAM disk is 512k with the sectors and directories parameters set at the default level (64-byte sectors and 64 directory entries). With DOS, a RAM disk could significantly improve system performance, but because OS/2 handles your memory far more efficiently than DOS and has its own sophisticated caching routines, using a RAM disk is not recommended.

CAUTION: Because a RAM disk takes available memory away from OS/2, you may negatively impact system performance on systems with less than 12MB of RAM. Unless you have lots of RAM or have a very specific need, don't install a RAM disk.

NOTE: If you do install VDISK.SYS and you also have EXTDSKDD.SYS installed, VDISK.SYS must be placed after EXTDSKDD.SYS in your config.sys file. Check your on-line Command Reference for information on EXTDSKDD.SYS.

TIP: Better use the RAM(64).IFS by Karl Olson, see IFS.
