 * Microsoft Paintbrush for MS-DOS, version 4.0

SUMMARY
When running Paintbrush for the first time, you may get one of the following messages:

Unable to access Virtual Disk

"or"

Unable to init Virtual Memory

This happens when the TMP variable is set incorrectly. You need not have a TMP variable, but if you do, certain actions will take less time such as cutting and pasting. To set up a TMP variable, add the following line to your AUTOEXEC.BAT file "SET TMP=C:\TMP" where the path C:\TMP points to an existing temporary directory. You can also set the environment by typing the above line at the DOS command line.

If you have set up a RAMDISK using extended or expanded memory, you can set your TMP variable to that disk. This can be done with the following two lines: MD D:\TMP

SET TMP=D:\TMP Please note the lack of spaces between the drive designator and path.

Please consult your DOS manual for information regarding setting up a RAMDISK. Additional query words:
