Remarks
VDISK allows the user to partition some of the computer's memory as a
disk. This disk is called a RAM disk or Virtual Disk. A RAM disk is
much faster than either a floppy or hard disk. The RAM drive can use
either standard DOS program memory or extended memory (above
1 MB) for the disk.
Any data on the VDISK is lost when the system power is turned off.
Example 1
DEVICE=VDISK.SYS
The above example builds a 64K RAM disk in DOS memory.
Example 2
DEVICE=C:\DOS\VDISK.SYS 220 /E
This example builds a 220K RAM disk in extended memory. The
VDISK device driver is loaded from the C: drive and the \DOS direc-
tory. VDISK assumes the default 512 byte sector size, and 64 directory
entries.
Example 3
DEVICE=VDISK.SYS 45 128 18
The above example builds a 45K RAM disk in DOS memory. There will
be 128 byte sectors and 18 root directory entries.
Example 4
DEVICE=VDISK.SYS /E
On a 2 MB system, the above example allocates a 1024K drive in ex-
tended memory (960K is allocated if DOS is loaded HIGH).
