i install 1.4rc3 on a ultra80. my partitions are
/dev/sda1 /boot
/dev/sda2 swap
/dev/sda3 /
/dev/sda4 /home
i put my vmlinuz as /boot/vmlinuz-2.4.20
but when i use silo to boot. it tell me can not open /boot/vmlinuz-2.4.20 and "unknown ext2 error".

does anyone see this before?

You might need to put your silo.conf on the /boot partition

What I do is this

Put my silo.conf in /boot/etc/silo.conf

then run silo as follows

silo -C /boot/etc/silo.conf

hTH,

i try u method.
i put silo.conf under /boot. and run silo -C /boot/silo.conf

or

I put my vmlinuz-2.4.220 under / and run silo -C /etc/silo.conf after modifying silo.conf

still same error, can not find /xx/vmlinuz-2.4.20 and unknow ext2 error.
and everytime i reboot, it saids /dev/sda3 not succ unmounted , need fsck. so i guess it is accessed when silo.
so what's wrong? it is related to silo or my ext2fs? i include ext2 in my kernel, but it seems not find kernel file and read it yet.

If you haven't already, I'd check out the booting portion of the UltraLinux FAQ located at
http://www.ultralinux.org/faq.html

Let me know if that helps at all.

i solve my problem. i modify the silo.conf and set the partition=3 (my previoud value is 4). in fact, i am not quite understand the meaning about this.
then i put my vmlinux under / and then silo can find it. but silo reports size exceeds error. i forget the exact msg. then i recompile it by set more as module and new vmlinux is around 2.5m. then it can boot now. now i have network ready. but the text screen seems only occupy part of the screen. does anybody know how to solve this?

thx so much for the hints u gave to me

I had the same issue today.

It seems a separate /boot partition is NOT advisable on Sparc. There is lots of handiwork needed to make it work.

The documentation will be updated soon to advise on this issue.

yes, i can boot from / while can not boot from /boot. maybe there are some trick in silo.conf we do not know.
