First, try to read relevant Debian bug info about booting on IBM CHRP machines:


It has almost all information needed to get Debian 3.1 'stable' image to boot.
Please note that 'testing' or 'unstable' Debian CDs do not have this problem!

I have seen a better instruction somewhere (the one I followed to make a boot CD
for my 7025-F50) but cannot find it right now. I will try to reproduce the
instruction on how to do it. First, mount your boot CD (or CD image using mount
-o loop debian-stable.iso /mnt). Then, create a /tmp/deb directory. Then:
 cp -a /mnt/* /tmp/deb; cp /mnt/.* /tmp/deb

The latter cp command copies .diskinfo file, so installer will recognize disk
later on.


mkdir /tmp/deb/etc
cp /tmp/deb/install/yaboot.con* /tmp/deb/etc/yaboot.conf

this will copy yaboot.conf file to the place where yaboot expects it (/etc on
the CD, not /install)

vi /tmp/deb/etc/yaboot.conf

mkdir /tmp/deb/ppc

and save file, attached to this message as /tmp/deb/ppc/bootinfo.txt
this file is needed by IBM Open Firmware to find yaboot boot loader

now, change all occurences of cd: to cdrom: , as IBM open firmware had cdrom:
alias by default for CD drive. Save the file.

then, create new ISO image with -l option (so long file names will be allowed):
mkisofs -r -J -l -o debian-new.iso /tmp/deb

then, burn the new ISO image to the CD by using cdrecord in Linux or any CD
burning program in Windows (I prefer Nero Burning ROM).

This CD should boot on your H50.
