After all devices initialized, call do_vgabios?

Ron,
I just got the vgabios emulation working in the LinuxBIOS. The VGA card is complete inited before the kernel is loaded. Now I have vga console just like normal bios system.
I will try the reduced x86emu and see if it works too.

No. The do_vgabios is depreciated and is removed from the CVS. It uses a real mode switch which is very difficult to to debug and not portable. The prefered way now is to use the emulator to execut the VBIOS. The emulator is acting as the .init method of a generic vga device driver.

THe really cool thing about this is that it is portable to, e.g., Power PC.

As soon as Ollie gets this into CVS, I'll try it on the sandpoint.

I guess this means that this is a V2 only thing. Looks like a 440bx port to V2 will be in my near future.
Would it be difficult to backport it to V1?

Richard, I think moving forward is your best bet. Since the last round of changes V2 has settled down and it is pretty nice.

Longer term I totally agree but our current setup also uses LILO so I'm still dependent on ADLO. Which means I would have to port all of that forward.
In due time V2+filo or V2+kernel&kexec is where I'll be headed but I'm just not in a position currently to rewrite my entire setup.

ok, then I'd go with Ollie's suggestion of a backport. Actually, it's interesting to note, for a lot of ports V1 is still a pretty handy system to use, since V2 is covering such complex systems.

If you don't feel bad to do it in the way as V2, it is not difficult to port to V1.
