Win95 desktop drive icons come from the TSD portion of VFAT.VXD
recognizing a physical device when it "arrives" and exporting a
logical device.

VFAT.VXD only exports logical devices ("volumes") for DOS Primary
partitions and DOS Secondary partitions on DOS Extended partitions
in the Primary partition table.

Your floppys and CDROM are seperately exported by the driver as
removable media.


Now, what you did:

You installed BSD to the second drive, and told it to install a boot
manager.  This actually does not work too well.


You need to shutdown Win95 to the DOS prompt after downloading the
DOS install for the OS-BS program.  By shutting down to DOS instead
of booting from a DOS (or BSD) floppy, you guarantee a boot to a DOS
prompt off the hard drive.  You need this because you might have an
MBR geometry translator for your IDE drive -- like OnTrack DiskManager
6.x or 7.x, etc..

With a boot to a DOS prompt of the hard drive in effect, you can use
the DOS-based install for the boot manager and it will go to The Correct
Place On The Boot Disk.  This will either be replacing the real MBR
(if you don't have OnTrack or a similar MBR-based INT 13 redirector TSR),
or by replacing the logical MBR (if you do have OnTrack, etc.).


Now when you reboot of the boot device, it will give you the option of
booting DOS (Windows95), or booting from the second drive (FreeBSD).

If you choose the second drive, and there is a boot manager installed,
then you will be given a choice of FreeBSD or the "second drive".  So
with a boot manager on the second drive, your life is more complicated,
but you will be able to boot FreeBSD..

For "use whole drive for FreeBSD" on the second drive, the boot manager
for the first drive will immediately boot FreeBSD -- assuming the
partition has been marked active.
