Thank you to all who replied to my query.
Problem: A user improperly shut down their Sparcstation, corrupting the
boot sector, rendering the machine unable to boot. The actual data on
the partitions was unaffected.
Suggested Resolution: Run "installboot"
Boot from Cdrom: boot cd -sw
fsck the boot disk: fsck /dev/rdsk/c0tXd0s0
mount the boot disk: mount /dev/dsk/c0tXd0s0 /mnt
find the appropriate boot block: cd /usr/platform/`uname -i`/lib/fs/ufs
Run the installboot command: installboot bootblk /dev/rdsk/c0tXd0s0
Reboot the system.
Unfortunately for me, this didn't do the trick. My end resolution was to
reinstall the OS, performing an "upgrade" rather than initial, to
minimize the impact.
