Yes, I was in the process of trying that when I received your message.
Here is where I am:
ok boot cdrom -s
# fsck -F ufs /dev/rdsk/c0t1d0s0
BAD SUPER BLOCK: FRAGS PER BLOCK OR FRAG SIZE WRONG
USE AN ALTERNATE SUPER-BLOCK TO SUPPLY NEEDED INFORMATION;
eg. fsck [-F ufs] -o b=# [special ...]
where # is the alternate super block. SEE fsck_ufs(1M).
I looked at that man page on the web, but am not sure how to
proceed. I just ran the above command earlier today when fsck
failed during a boot, without receiving that error message.
After fsck runs successfully, I was going to restore the boot program
from the installation cd as follows:
# cp /platform/`uname -i`/ufsboot /mnt/platform/`uname -i`
Any comments about this?

Unfortunately, I do not have another scsi chain on which to do this.
I would need to install another scsi card -- maybe a good idea at this
