So it is hd:3 and then, openbios dies directly :

As a starting point, can you provide the contents of the root of the HD image as given with:

That system was updated from Mac OS 9. That might be the issue.
Ah that could be it indeed. I've heard reports from people that installing Classic mode into a QEMU OS X causes it to fail to boot, but no-one has been able to provide an image to date. But it definitely looks like the right partition.
(it's much easier to cut/paste if you run qemu-system-ppc with -nographic). This is just to ensure that a HFS+ FS isn't accidentally getting picked up as a HFS filesystem (some driver partitions are set up this way).
How do I add more logging with openbios ?
You should find that in -nographic mode Forth errors are logged to the console - does anything obvious stand out? If not, you'd probably have to look at modifying OpenBIOS to dump out the 10.5 bootloader to see what it's trying to do.
yes. I will look into that next.
Using -nographic, I get more info : "Not a bootable ELF image". That's something to look for !
That just means that OpenBIOS scanned through its list of recognised binaries and didn't match on ELF - presumably from your previous email it is a bootcode image, i.e. XML, possibly with a payload, so it would have subsequently recognised and matched on that.
You could try seeing if just loading the binary succeeds without invoking the failure on seek, and then follow this up with a go to execute the image directly:
load hd:3,\:tbxi go
If it freezes on go then that means its something in the bootloader failing in which case you may get further information by either enabling debug in the device tree:
cd / ffffffff encode-int " AAPL,debug" property boot
or perhaps passing the verbose parameter via the QEMU command line, e.g.
-prom-env 'boot-args=-v'
FYI, I had to specify the path of BootX to get running.
Oh great! Is this something that could be added to the list of paths OpenBIOS searches for an executable on boot? If you can suggest a suitable place in the ordering, the patch to add it is fairly trivial.
ATB,
Mark.
