Andreas did some preliminary patches for OpenBIOS to support PReP machine= s, available at git://repo.or.cz/openbios/afaerber.git branch prep. 43p emulation has been tested with this firmware, and also with the offic= ial firmware, named P93H1904.IMG. Command line may look like qemu-system-ppc -M 43p -readconfig ibm_43p.cfg -device ide-hd,drive=3Dhd0 -drive if=3Dnone,id=3Dhd0,cache=3Dwriteback,fi= le=3D"hda.qcow2" Changes RFC v1 -> RFC v2: - rebased on master - works with OpenBIOS - rework on m48t59 patches - remove rs6000 debug port emulation (not strictly required) - checkpatch.pl doesn't complain anymore Known bugs/missing parts: - incomplete MPC105 (PCI host bridge) emulation (memory controller) - no video card (should be a S3) - QEMU can't change endianness at runtime OpenBIOS status: - detects CPU and memory, then freezes with a "Dictionary space overflow" Official firmware status: - can boot from a IDE hard disk containing a PReP boot partition - can't boot from IDE cdroms (overlapping commands not supported by QEMU = IDE emulation) - can't boot from floppies (READ commands are issued, but it seems comple= tion is ignored) - can't boot from network (detects the netcard, but doesn't use it) - needs a hack to m48t59 device to work (patch 7/7) Please comment.
