Anybody: What's the recommended
approach/reference/magic to getting video
going for LinuxBIOS. I'd like to get the on-chip video going on
the VIA Epia
board - Hints appreciated.
Do you mean a linuxbios vga text console?
I have the code to set the legacy registers to start VGA for a vga console,
integrated into linuxbios, working on two different integrated chips, the
stpc cpu/chipset, and the sis 630 chipset. It sets the registers for
640x400 std text vga, and also 640x480x4 graphics. I was working on the
display of a .pcx graphics file when I had to get onto something else, but
it was all working the last time I tried it.
You are welcome to the code if it would help. AFAIR the EPIA is the
PLE133/vt8601a, which has legacy VGA registers. All you need usually is
legacy plus a "few other settings" to get text and/or simple legacy graphics
going. The "few other settings" can be bitch, though.
