vgabios and PCI data.
PATCH 1/1 vgabios and PCI data.
attached patch to vgabios-0.6a adds the pci data structure to vga-cirrus.bin
This is needed to boot LinuxBIOSv3 with VGA enabled on Qemu
It seems the vgabios project has stalled, so I am sending this patch to this list as well. Can you update the vga-cirrus.bin image to include this pci data structure?
