Er, I never saw your post on debian-sparc ... taking it back there.

Of course it did; even though you installed your kernel in /boot, SILO
still thinks it's installing from / (the large partition). Thus, SILO
cannot read its own config file due to the buggy boot PROM problem.
Solution:
First, edit /etc/silo.conf and make the following changes:
* the "partition" directive should specify the partition /boot is on.
Thus if /boot is /dev/sda1. silo.conf should have "partition=1".
* each "image" directive needs to be changed so that it lists the
kernels _as they appear in /boot_; the symlinks in / _are not visible
to silo_. THIS IS IMPORTANT! You'll end up with something lioke
this:
image=1/vmlinuz-2.4.18
label=2.4.18
root=/dev/sda2
read-only
* run the following commands
# mkdir /boot/etc
# cp /etc/silo.conf /boot/etc
# ln -sf /boot/etc/silo.conf /etc/silo.conf
# silo -r /boot

cylinder 0 works fine for ext2, ext3 partitions. I had some trouble
when experimenting with other filesystems; for instance creating an
XFS filesystem on a partition starting on cylinder 0 overwrote the Sun
disklabel.
