There is a bug in the code that prohibits the use of Xega on ega
monitors the code to the best of my knowledge only works on vga. I
don't have the space to fix it anymore.
The fix is pretty simple. All that needs be done is the config code
that reads the register values needs to be caned and instead hardwired
values need to be used. on the vga if I remeber correctly you could
read and write the registers and on the ega you could only write them.
for the ambitious ega user he might just take the init code and can
the part that saves the current register state. The only reason I do
this is so you can restore the monitor to the correct mode.
