Execute VIDEOID to identify the type of video adapter(s). The information is
written both to the screen and also to a text file named VIDEOID.TXT
The first six steps, identifying the installed video adapter(s) are based on
routines from Richard Wilton's "Programmer's Guide to PC and PS/2 Video
Systems" (Microsoft Press, ISBN 1-55615-103-9) with minor modifications to
identify 64k/256k EGAs.
If an EGA or VGA is detected, a seventh step dumps the first 216 bytes of
video RAM to show the manufacturer's copyright notice.
If a VGA is detected, step 8 attempts to identify the chipset manufacturer
and the amount of video memory, if possible. These routines are primarily
based on John Bridges' VGAKIT with modifications and additions. VideoId adds
detect routines for 8514/a and the Hercules Graphics Station and additional
memory tests, where available.

The Herc GS "1meg" result is plugged. The Paradise memory routine seems to
be working on a variety of Paradise cards and clones. The Tseng 4000 routine
is new in version 1.3, and we need reports of test results.
