If the demo does not run from hard disk, the installation likely did not
complete.  Check to see that there is at least 600k of free space.
Delete some files if necessary and try again.

If the installation still doesn't succeed, try running the demo from
the floppy disk.  The disk may have been damaged in shipping, in which
case contact us for a new diskette.

If you do not have 640 x 350 EGA, 16 colour support, the demo will
not run at all; a message will appear on startup indicating so.

If the demo crashes midway through, you may not be in 80 column, colour
text mode.  At the DOS prompt, type:  mode co80    and try again.
