Hi,
after a lot of attempts, I was able to reach some progress.
I have figured out, that the 5.x.x version Debian PPC CDs are not
bootable on PReP machines.
The older 4.0rX images can be booted, as they contain a PReP boot image.
I was able to load the kernel, but it is very-very slow (8-10 minutes
until the first messages show up), and the boot process hangs, when
loading the initrd image:
RS/6000 RS/6000 RS/6000 RS/6000 RS/6000 RS/6000 RS/6000 RS/6000 RS/6000 RS/6000

checking if image is initramfs... it is
I have also tried booting 3.1rX series Debian CDs, but to this point I
had no success with the firmware command:
boot cdrom:,\install\powerpc\vmlinuz-prep.initrd
I have read the How-Tos you linked and found the following to be the
most helpful:

I have also tried to boot from floppies, but it didn't work either.
I was trying to boot the Yellow Dog Linux floppy images, that were
downloadable from:
http://users.linpro.no/ingvar/43p/images
It managed to boot up to a certain point, where it was caught in a
loop, while trying to reset the Symbios integrated SCSI controller.
I will in the next few days try to boot the other (Debian, SuSE and
Mandrake) floppy images. Maybe they will not have this problem.
Anyway, I will report back, if I have some further progress on this matter.
Regards,
Janos
