I want to rebuild the kernel with a new tape device, but current "unix"
boots to a panic, so I must boot from unix.old....When I rebuild, I want
to be able to boot from a backup "unix" kernel in case new rebuild fails
for some reason......Any help is greatly appreciated. /stand is mounted
as protected (no read or write).

Thanks

Simply copy the unix.old to unix.good and do whatever you want with the
kernel config and re-build... You can always get booted from the : prompt
typing unix.good

So unmount /stand, and re-mount it read/write.
#umount /stand
#mount /dev/boot /stand

Of course, it sounds like you can't boot into unix now, so renaming the
kernel is not much help. Here's what you do: At the "boot:" prompt, just
type unix.old then press enter. That will use unix.old as the kernel.
Then, when the system is running, do a "cp unix.old unix" (assuming you
don't want to keep a copy of your bad kernel).
