Yes, definitely. The graphics card bios will reinitialize the card in VGA mode, so Linux will be definitely confused if it suddenly has no pixel based graphics mode anymore.
Yip, I have start the system with vga=normal and taken a fresh vga.bios extracted with awardeco from the original factory bios. (The old one was definitivly corrupt)
btw. flashbios seems unable to handle WINBOND W29C020
./testbios --abseg /dev/mem -s 32768 aw512n.bin
I get 3 columns of output, which stops after 1-2 seconds The screen seems froozen, but at the bottom I have 3 blinking "cursors" I can do what I want, only a Hardreset takes effect ;)
I will try to pipe the output, but this is hard on a readonly filesystem :D
