VGA480.COM is a PRELIMINARY resident program which permits the Eva/480 to
emulate the IBM VGA modes 11h and 12h using the Eva/480 640x480 graphics mode.
Also, setting the the most significant bit (MSB) permits mode changing without
clearing the screen contents.
VGA480.COM allows programs which support the IBM VGA 640x480 modes to run on
the Eva/480 without the need for modifications. Simply run VGA480.COM and
install the application software for use on the IBM VGA 640x480 mode.
Note, VGA480.COM remains resident and needs to be loaded only when the system
is first powered on.
VENTURA ver. 1.1 supports the IBM VGA 640x480 and will work
with this program.
NOTE
Not all IBM VGA programs will work using the emulator. The IBM VGA 320x200
256 color mode CANNOT be emulated. Also, programs which make use of the
I/O register readback capabilities of the IBM VGA will NOT be able to do so
on the Eva/480 and may not work.
