Well, not a lot, but still...

I've given another shot at booting my PM7200 (whose problem is having a=20=

PPC601).

I've modified ofwboot.xcf and now it loads the kernel file.
See attached (rough) patch.

Then either it hangs if I load an uncompressed kernel, or there is=20
DEFAULT CATCH!, code=3DFFF00700 (see below) if it is gzipped.

How can I tell if it has jumped into the kernel, or if it is not there=20=

yet ?

My guess is again a problem with BAT mappings.
The current code maps the first 256Mb block.
The 601 can only map 8Mb regions. I tried to map the first four.

Any idea ?

Regards,
