Great! Thank you for the heads-up! > Apart from the BaseTools breakage, I also don't seem to have video until > SeaBIOS itself starts.

I note in > http://www.linux-kvm.org/page/OVMF > there is a reference to vgabios-cirrus.csm.bin... I think the SeaBIOS binary in Fedora 19 is *not* buggy in this regard. I assume though that SeaBIOS and/or SeaVGABIOS in Fedora 19 are not built with the correct config options for CSM. I use the following config options when building upstream SeaBIOS and SeaVGABIOS for CSM (note that this is two separate builds): SeaBIOS: cat >.config <<-EOT CONFIG_CSM=y CONFIG_QEMU_HARDWARE=y CONFIG_PERMIT_UNALIGNED_PCIROM=y CONFIG_DEBUG_LEVEL=20 EOT yes "" | make oldconfig make -j2 out/bios.bin mv -- out/bios.bin "$SIDE_COPY"/Csm16.bin SeaVGABIOS: make distclean cat >.config <<-EOT CONFIG_QEMU=y CONFIG_BUILD_VGABIOS=y CONFIG_VGA_CIRRUS=y CONFIG_VGA_PCI=y CONFIG_DEBUG_LEVEL=20 EOT yes "" | make oldconfig make -j2 out/vgabios.bin cat out/vgabios.bin >| "$INST"/vgabios-cirrus.csm.bin These were shamelessly stolen from one of Gerd's SRPMs (the DEBUG_LEVEL setting is mine). I'll admit however that it's been a while since I last rebuilt these binaries.
