I'm running Minix 1.2 on an Intel 80286 Board with a Paradise Autoswitch EGA.
Using the Autoswitch feature I have the same problem, so I boot MS-DOS, use
EGA-tool to lock the current mode and boot Minix. ( Only Hardware Reset resets
the EGA-Card ). This solves the problem for me.
That's no satisfying solution, but until I've hacked the error, it works.
The problem for me is to get a description of the Paradise Autoswitch EGA
control registers. So if somebody could tell me where to get one, I'll try to
fix this bug.
