I've had problems in the past with some Powerstack systems not being able
to boot a PReP image from anything other than /dev/sda1....since then I've
been recommending everybody just install the image to sda1 and root from
I tried to recreate you problem because I didn't think it existed on our
newer PowerPlus systems. I slapped a PMC101 in a MVME2431 in the rack and
installed Debian/PowerPC to it with sda1->swap, sda2->root, and
sda3->prepboot with no problems. It made the system automatically
bootable from sda3 and a "pboot 10 40" (disk on SCSI ID 4) booted up.
Can you post a dump of your partition table on the disk plus the first 1k
of the image? I have seen the error before somewhere but I think that was
on a byte swapped IDE system the PPCBUG couldn't read...SCSI doesn't have
that problem..bad bad IDE.
