Just having a quick look at the sources: These days qemu stores the vgabios in the ROM bar of the emulated vga card. Thus it needs a proper PCIBIOS header, otherwise SeaBIOS will not load it. > However, the vbe extensions weren't > present, and so most guests wouldn't attempt to increase resolution or > they had other features not available. Pretty normal behaviour without VBE ;) > Also, I was seeing the grub > screen come up as black-and-white - which may be due to lack of VBE, > but may also have been due to a bug somewhere in the port. Hard to say without more details. grub can use gfx mode and come up with a fancy background picture. That isn't upstream though and different distros use different patches to do this. Might be at least some versions depend on VBE for this. grub has a text mode fallback. That can be colored too, depends on the configuration, by default it is black-and-white. cheers, Gerd -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
