Booting an Ultra 1

[Eric <eric-list-openbsd_(_at_)_catastrophe_(_dot_)_net>]

I have the following problem when booting a Sun Ultra 1 (by the
looks of the archives, it's probably an older openboot problem)...

solaris# dd if=miniroot32.fs of=/dev/rdsk/c0t0d1s3 bs=64b
solaris# reboot

I send a break and then..

ok boot disk:d bsd
Resetting ... 

Sun Ultra 1 SBus (UltraSPARC 167MHz), No Keyboard

Rebooting with command: boot disk:d bsd                               
Boot device: /sbus/espdma_(_at_)_e,8400000/esp_(_at_)_e,8800000/sd_(_at_)_0,0:d  File
and args: bsd
OpenBSD IEEE 1275 Bootblock
.Bad path

To show some diagnostics...

I assume his is a very old boot loader?

If so, I can boot to Solaris, but is there a listed patch to
upgrade?

Thanks.
