(I'm wondering if we should start a new thread here either just on qemu-ppc or over on the OpenBIOS list) OpenBIOS will read hfs/hfsplus filesystems fine - I wonder if maybe it can't locate a suitable partition in the Apple Partition Map? If you boot to the Forth prompt with -prom-env 'auto-boot?=false' can you try the following to see if you can list the disk contents: dir hd:,\ If that doesn't work it means that the partition auto-detection is failing, so try manually forcing the partition number until you find one that works e.g. dir hd:0,\ dir hd:1,\ etc. up until around partition 10? Once you find one that works it should be possible to boot that partition directly e.g. boot hd:1 ATB, Mark.
