Memory Device Drivers
RAMDRIVE.SYS
A RAM disk is a portion of your computer's memory configured to simulate a disk drive.
Such a disk, which may be called a virtual disk, can be accessed much faster than a
normal disk drive.
The data stored on a RAM disk disappears when computer power is turned off, so you
must copy the contents of the RAM disk to a floppy disk or to the hard disk before turning
off power. You can do this using the furnished Laptop File Manager utility or the MS-
DOS 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 require 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 KB,
and the default value is 64 KB.
Several other options are available for setting up a RAM disk. Refer to your BatteryPro &
Productivity Software User’s Manual for details.
The RAM disk is given the drive letter that follows the last drive letter being used by your
system. For example:
q If your hard disk is configured as drive C, the RAM disk is drive D.
q If your ROM disk is drive C and your hard disk drive is drive D, the
RAM disk is Drive E.
