Which qemu version? Which seabios & vgabios version? Windows xp booting in 4bit usually indicates VBE doesn't work at all, trying to enable vesafb in linux fails too then. I havn't seen this for a *long* time. Last time was a year or so back, while shaking out vgabios issues. Especially I've never seen that with any qxl/spice stuff in upstream qemu. Thats why I'm wondering where this comes from? cheers, Gerd
