Subject: FreeBSD 1.1.5.1: Can't mount PCFS filesystem

I have a 486DX50 running FreeBSD 1.1.5.1. The system is configured with
an AHA1542B and two SCSI disk drives. When I want to run UNIX, I change
the internal (DOS) drive to SCSI ID 1, power up the external (UNIX) disk
as SCSI ID 0, and boot UNIX. When I want to run MS-DOS, I change the
internal drive to SCSI ID 0, power off the UNIX disk and boot up DOS.
Works GREAT! Now...

When I'm running FreeBSD, I want to mount the DOS partition from SCSI
ID 1 (/dev/sd1?) but this doesn't work. The man page on mount-pcfs seems
to imply that this will not work unless there is a FreeBSD label on the
disk and the DOS partition is SHARING the same disk with UNIX! Why not?!

Note that trying to mount /dev/sd1d yields a different error message
than /dev/sd1[abc].  Perhaps 'd' indicates DOS partition's position
in the DOS partition table?

# mount -t pcfs /dev/sd1a /dos
sd1: no disk label	[bright/from-the-kernel]
mount: Device not configured

# mount -t pcfs /dev/sd1d /dos
sd1: no disk label	[bright/from-the-kernel]
mount: Invalid argument

I think using seperate disks for DOS and UNIX is a MUCH better solution
than sharing, and is wonderfully easy using SCSI. Above all, I want to
avoid trashing my DOS partition (which I have done many times playing
with various PC UNICES). This scenario seems to have been ignored.

Now that I have loaded up my DOS disk, is there a work around or a fix
available? I don't believe I can re-label my DOS disk without trashing
the DOS partition.

I believe BSD386 from Berkeley Software Design got this right...
what gives?
