[I have not been following this thread so forgive me if you have already
covered this]
There is at least one MBR replacement that not only allows selection of
the paritition to boot from but, more importantly for this discussion,
allows booting from paritions on other drives. OS-BS is not one of them
(the author considered it but there was no more code space left). I vaguely
remember another one called "bootp" or something that I think did support
this. This should allow the 386BSD primary and secondary boots to be on
another disk.
There was a thread on this about a month or so ago when someone was trying
to do just this (then again, this might have been one of you ;-)).
I never read a posting on whether it was successful or not.
I seem to have one of the postings. In
"booting-up "386bsd" from the 2nd-Hard-Drive", nemossan@uitec.ac.jp talks
about using a boot program called "assistIPL" from a package called
"MXboot" originally developed for Minix. Search the archive at minnie for
this subject line and see what turns up.
