Added support for the video mode switching hotkeys to match the stock Compaq BIOS:

  • ctrl-alt-, for MDA mode
  • ctrl-alt-. for CGA mode

TODO

  • cursor handling isn't correct yet; tends to get set in the middle of the line vertically
  • test with an external CGA monitor
  • test with a Compaq EGA card

I've also disabled POST_TEST_FD since it seems to always give me error 0800, under emulation in 86box and with real hardware (I've tried two floppy controllers).

I have this running on a real Compaq Portable. I would still consider this to be preliminary support, but it's good enough for me to leave in the machine.
