mtouchxl.cpp: Merit Industries MegaTouch XL
Hardware includes a base 486? PC with VGA and a customized ISA I/O
Hardware includes a base 486 PC with VGA and a customized ISA I/O
card. The I/O card includes audio and an option ROM which patches int 19h
(POST Completed) to instead jump back to the option ROM which loads
"ROM-DOS", installs drivers for the Microtouch screen, and then boots
from the CD-ROM drive.
Currently: ROM-DOS loads and installs virtual drive C:, but things go wrong
in a hurry after that :)
Audio is a CS4231 combination CODEC/Mixer also found in Gravis Ultraound MAX
and some SPARCstations.
