RAMDRIVE.SYS
A RAM disk is a portion of your computer's memory configured to simulate a disk drive. Such a disk can be
called a "virtual disk" and can be accessed much faster than a normal disk drive. The contents of a RAM
disk disappear when power is turned off, so some action must be taken to copy the contents of the RAM disk
to a floppy disk or the hard disk before turning off the power. You can do this using the COPY command to
copy all files from the RAM disk, or you can set up a batch file to do it automatically. Unlike a normal disk,
a RAM disk does not need formatting before use.
To set up a RAM disk, include the following line in your
CONFIG.SYS
file:
DEVICE=C:\DOS\RAMDRIVE.SYS [size]
Specify the size in kilobytes. The minimum size is 16 K byte, and the default value is 64 K byte.
There are several other options which can be used when setting up a RAM disk. Refer to your MS-DOS
User's Manual for a full description.
The RAM disk is given the drive letter that follows the last drive letter being used by your system.
‰
If your hard disk is configured as Drive C the RAM disk is Drive D.
‰
If your ROM disk is Drive C and your hard disk drive is Drive D, then the RAM disk is
Drive E.
