This is the whirl expected:

Automatic boot: black screen and automatic reboot of the box.

Manual boot:

I had a look on the cdrom and found in \ppc a bootinfo.txt saying the script 
was \ppc\chrp\yaboot, just similar to what I have seen on the AIX CDrom. 
(bootfile.exe in lieu of yaboot).

So boot cdrom;:\ppc\chrp\yaboot gives me:

unexpected firmware error
default catch code ff00300
$RR0 00c1b030
$RR1 00003030

and back to the OF prompt.

I suppose in automatic mode this leads to a complete reboot of the machine, 
just as observed.

I founded in /install/powerpc a vmlinuz-chrp.initrd dated today.
I supposed it is the patched one.

So boot:;\install\powerpc\vmlinuz-chrp.initrd

"Unable to use memory at load-base"

printenv load_base   4000


Just a question more: don't whe have to find a yaboot.conf in \ppc\chrp if it 
is the directory from which we intend to launch yaboot ?
