SUMMARY: Fcode sequence error

From: opeth <>

Here were some of the suggestions/explanations I received about the Fcode
problem below:
1) SCSI termination problem
2) Bad CPU
3) set-defaults at ok prompt to reset nvram
4) Dead battery or boot chip failed

None of this turned out to be the case or fix the problem.

For the heck of it, I tried replacing the bootblock and that fixed the
problem! To do this, I booted from a working disk, mounted the non-bootable
disk to /mnt and then typed the following:
installboot /mnt/usr/platform/`uname -i`/lib/fs/ufs/bootblk
