Memory Device Drivers
Note: When using Windows 3.0, always use the HIMEM.SYS device driver included
on your Microsoft MS-DOS 5.0 floppy. See 'EMM386.EXE" earlier in this appendix for
operating instructions in 386 enhanced or standard mode, and see your Windows and
MS-DOS manuals for more details.
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 CON-
FIG.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.
