Severity: grave

Justification: renders package unusable

Problem on Installation for Debian on IBM Risc/6000
Hardware is IBM RS/6000 B50 (model 7046), 128 MB Ram, 9GB SCSI HDD
Architecture is CHRP. ps/2 keyboard+mouse S3 pci video.

While trying to install debian on an ibm rs6000 B50 (i have 4 i want to
use!) i want to report the problems i have.

First, i downloaded the sarge boot image (speaking of the 'netboot'
minicd iso image) and i cannot boot at all. with the hard disk
completely wiped the system keeps resetting himself. evidently it cannot
boot form any boot device and remains stuck in the boot process polling
devices (floppy, cd, hd, network) for a boot image. Following some
instructions found via google, the debian-boot ml and others, i
downloaded the current netboot and tried to install from it.

Getting debian installer on 10 Feb 2006, 18:14 CET
Copy file from:
http://cdimage.debian.org/cdimage/daily-builds/daily/arch-latest/powerpc/iso-cd/debian-testing-powerpc-netinst.iso
Burned on cd/rw media
the B50 server cannot boot.

In order to go to the yaboot prompt, i have done this procedure:
(workstation with debian/testing on Athlon64, all packages at current
revisions)

mounted the netinst to my workstation's /mnt/disk via "mount
/space/debian/debianiso/debian-testing-powerpc-netinst-20060210.iso
/mnt/disk -t iso9660 -o ro,loop=/dev/loop0"
copied contents to hard disk via "rm -fr disk ; rm -fr /space/debian/ppcboot-20060210 ; rsync -a /mnt/disk /space/debian ; mv /space/debian/disk /space/debian/ppcboot-20060210"
unmounted cdrom image via "umount /mnt/disk"
cd /space/debian/ppcboot-20060210/ppc
Modified the bootinfo.txt file (see patch attached)
cd /space/debian
created new image by "rm -f /space/debian/ppcboot-20060210 ; mkisofs -chrp-boot -U -r -hide-rr-moved -V "Debian testing ppc Bin-1" -sysid "LINUX" -o /space/debian/ppc-testing-20060210.iso /space/debian/ppcboot-20060210"
Burned on cd/rw media

Now disc boot to yaboot ok.

It seems to me that the B50 openfirmware does not recognize the
bootinfo.txt file as valid if it doesn't contain the icon description
along with the other tags.

hope this helps.
 Andrea
