The BIOS only boots from the first drive so the 386bsd bootblocks
have to be on the first drive (that's what the BIOS loads)

It would theoretically possible to have a version of EZBOOT or
os-bs that would load the unix bootblocks from the other drive.
(they replace the standard DOS sector 0 bootblock with something
a bit more intelligent (e.g. a menu with a timeout))

Failing the availablity of that,
the easiest thing to do is put a 10MB 386bsd root partition
on the first drive and mount the others from the second drive
once the system has booted. (you do need the patched kernel
that can handle a second drive but Most kernels should do that
by now, (the patch has been out as long as the kernel).

well not at the same time.. but you can boot to either with
an menu (see EZBOOT or os-bs (available on agate,)).

>3. Can it be booted using a floppy?
yes

>4. If it can be installed on a second system drive... how???
I suggest making a small partn on the first drive first
and then using fdisk to divide up the second drive and
disklabel to label the second drive and divide the 386bsd
part up into further 386bsd partitions.
then use newfs to make filesystems on them.
don't forget the cardinal rules:
1/ try use the same geometry for all OS's even if it means using a translated
	cylinder size under 386bsd.
2/ all partitions should start on a cylinder boundary
3/ all partitions shold end on a cylinder boundary.

there's more to it than that, but they should guide you past most 
pit-falls.

 if you can get to a 386bsd machine (e.g. ref.tfs.com (guest))
 do:
 man disklabel
 man fdisk
 man mkfs
 man swapon
 man fstab
