Hi,

for now, I'm fighting to merge latest changes from CVS.
I want to submit a big set of patches for next qemu version...
Current CVS cannot launch PPC systems.

Thanks for this tip !
I fetched the whole CDROM, and I'll try to add a correct OpenBIOS loader
as soon as possible.

Yes, this will be possible when the MMU emulation will be fixed.
I still have some crashes when my initial shell forks, so it's quite
"difficult" to launch a real distribution.
Could you build a tiny system disks for me to test more on your PREP
machine ?
I'd like to be have a static busybox disk and a dynamic one.
For now, I build cross-compiled images and this can be another source
of problems...
I'd also like to have a real kernel configuration for PREP.
I did some 2.4 & 2.6 kernel, intuiting parameters, but I'd like to know
what is correct on a real machine and see if I missed some hw parameters
on my emulated hardware.
