The OS can initialize the second head too. I don't think we need to initialize it in the boot phase.
Really? Which OS?
I.e. what assumptions are you making when you say "OS"? Linux?
Hi Ron,
It is my understanding that a COTS bios will only initialize the first VGA card. I know multiple vga cards work on at least Windows and Linux. I therefore concluded that these OSes can initialize secondary vga cards (at least with the proper drivers installed).
If I've missed something, please let me know.
In particular, if there is evidence that a COTS bios will swap option roms then I'll treat it as a requirement for seabios (and/or coreboot). However, I'm not interested in trying to make option rom processing "better" than a COTS bios - I think the whole option rom thing is a disaster - we do it for compatibility, not as a feature.
