Re: [Qemu-devel] New BIOS for Mac PPC target.

[Martin <qemumail@olifantasia.com>]

Because the current ppc bios does not run the cdrom I tried if it would 
run my previously installed OSX 10.3 harddisk image (installed with pearpc)

os10.img 2642411520 bytes (2.5 GB)
stops with:
quarkdeb:/pub/projects/emulators/hardfiles/ppc# qemu-system-ppc

It seems that it doesn't recognise the bootpartition/bootfile
In pearpc this image runs fine.

I also did another experiment.
In my working debianppc image I installed mol.
I tried to just run mol inside qemu-system-ppc
The mol kernel module seems to load ok but mol dies immediately 
afterwards with Oops: kernel access of bad area, sig: 11.
Before analysing why it goes wrong I would like to ask if you start qemu 
with qemu-system-ppc -prep -kernel vmlinuz-2.4.25  .....
Is it then still possible to load a 2.4.25 kernel module inside the 
guest or is this asking for trouble.

For completeness here is my startmol log.
