SVDISK.SYS

This is the driver for the Super Virtual Disk tool, which emulates a floppy drive in memory. Super Virtual Disk (SVDisk) is a 32-bit OS/2 device driver that emulates either a removable Virtual Disk (VDisk) or a removable Virtual Floppy (VFloppy) drive. By using OS/2's virtual memory management facility, SVDisk allows the entire contents of the disk to be swapped out via the paging mechanism. If the SVDisk is frequently accessed, OS/2 will keep the most recently used memory pages in RAM, SVDisk will essentially behave like a RAM Disk.

DEVICE=C:\SVDisk\SVDisk.sys <parameter>

Parameter:

• n

the possible values for VFloppy device are: 360, 720, 1200, 1440, and 2880. Use 1520, 1840 and 3680 for XDF VFloppy. Since SVDisk defaults to a 1.44MB VFloppy device, the 1440 parameter can be omitted.

• ssss

the size of the VDisk device. The possible values for ssss are from 16 to 131056 (16KB to 128MB.) The VDisk device will always round up the size into 16Kb boundary.

• eeee

(optional) the root directory entries for the device. Default 64
