Hi, I tried running linuxbios v3 in qemu again, and for some reason it didn't initialize the pcivga device, even though I have vm86 compiled in.
See this excerpt from the log: Phase 3: Enumerating buses... dev_root_phase3 missing 'ops' initialization Phase 3: Failed. Show all devs... Phase 4: Allocating resources... Phase 4: dev_root missing ops initialization Phase 4: Failed. Show all devs... Phase 5: Enabling resources... Phase 5: Done. Show all devs... Phase 6: Initializing devices... Phase 6: Devices initialized. Show all devs... I think, that the "missing 'ops' initialization" message indicates that the static initialization in the source didn't survive the build. I'm at r542, vgabios-cirrus.bin is a patched variant (includes the pci header), it's built using ubuntu's gcc-4.1.3(preview) on amd64. Any hints? Regards, Patrick Georgi
