Hi all,
A week ago, I finally gave (I have wanted to do it for a long time) linuxbios a try, and just for fun I enabled VGA support when I compiled it. The qemu build tutorial says nothing about vga so I guessed there'd be a reason, and of course there was. Neither console nor X works.
Is there a good reason for this? I suppose the qemu vga bios isn't your standard bios but rather some kind of vga card emulator, is that the reason? Would it be hard work to get it running or have I just overlooked something simple? I use FILO as payload to load debian 4.0 and most things except vga seem to work.
Oh, I just saw something about vga in the "dtc emits constructor array" thread, is my question already answered? I'm pretty new to this, have hardly even looked at code that touches the hardware since them '64 days... The last years I have mostly been coding in matlab.
By the way, are there any MCP55 motherboards in Microatx format? If I had a job (why is the demand for linux geeks so hopelessly low :( ) I'd love to get an X2 board that runs linuxbios, but full atx boards tend to make pretty big and bulky computers and I already have lots of them. Or if there's some other chipset for AMD that looks a lot like the mcp55 I think it could be fun giving it a try.

If you try Qemu, you should use LinuxBIOS v3. You also need a patch to the Qemu VGA option rom, because the current one lacks a PCI rom header.

Thanks. I just checked v3 out. It works, but still no vga. Where can I find the VGA patch? Is it any of the isa-bios or piix-ram-size patches mentioned on the qemu build tutorial or is it some other patch? Or is it a patch I'll have to figure out myself?
