Re: Testing GRUB from other distros.
To be clearer, Fedora's GRUB did work too. I was able to boot the
CD-image and I saw GRUB starting kernel/initrd, but this boot step failed.
So, as a matter of fact, GRUB as a loader for the kernels from the
CD-images always worked.
I can try Fedora with the CD image burned on an actual CD, but I
honestly do not expect any change.
Regarding OpenSUSE, the problem is at the step regarding drivers
initialization. The boot process always hangs when trying to load the
driver "ssb", that in my understanding has something to do with the
Broadcom WiFi interface. I do not understand why the installer was able
to start this driver at first and now it does not.
I also tried to exclude this driver by appending the line
"brokenmoddules=ssb" to GRUB's kernel line as suggested by the installer
itself, without improvements.
Errata corrige: the line to boot ISOs from OpenFirmware was:
"boot ud:,\\:tbxi"
and not:
"boot hd:,\\:tbxi".
Regards.
