Help!

We had a power outage, and when I brought my system (Solaris 10 3/05)
up, it would come only boot in single user mode, suggesting that i
could (with some risks) use svcadmin to clear the boot archive (i
can't remember the exact command). I did, and now the kernel won't
even load. Now I get:

[probably some stuff that scrolls by too fast to read]
cannot read biosint
trap type 13 (0xd) err code 0x98b8 eip=0x0
[bunch of register and stack trace data]
panic: unexpected trap in boot loader
Press any key to reboot

any help would be greatly appreciated!
