It might be in the FAQ. The FAQ is unofficial and is not posted
here very often. Look for it at agate.berkeley.edu in
/pub/386BSD/386bsd-0.1/unofficial/terry/FAQ.09Aug92.

Yep.

You certainly need a partition for 386BSD and another for DOS & Windows3.1.
I thought that OS/2 also required its own partition. 386BSD will work
within the DOS partitioning scheme or you can dedicate an entire drive to
it. Currently, it must still boot from the first drive (actually, I think
there was a project to lift this restiction, but I do not know if it has been
completed).
I heard that the IDE drives are tricky to configure for 386BSD. Check the FAQ
to see if there is any info on this.
You can certainly use FDISK to change the active partition bits to
select between the O/Ss, but a more convenient solution would be a boot menu
program. I use OS-BS (agate.berkeley.edu in
/pub/386BSD/386bsd-0.1/unofficial/terry/os-boot-select). It gives me a
menu a boot time to select between the O/Ss.
