VDISK.SYS

The VDisk Device Driver (VDISK.SYS) provides a virtual disk in RAM.

DEVICE=x:\OS2\BOOT\VDISK.SYS [bbbb] [ssss] [dddd]

Parameters

 * bbbb:Disk size in KB. Default value is 64 (16 ... 4096).
 * ssss:Sector size in bytes. Default value is 512 (128, 256, 512, 1024).
 * dddd:Number of root directory entries. Default is 64 (2 ... 1024). The value is rounded up to the nearest sector size boundary.
 * NOTE: In the event that there is not enough memory to create the VDisk volume, VDisk will try to make a DOS volume with 16 directory entries. This may result in a volume with a different number of directory entries than the parameter specifies.


 * 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.
