One line of attack that has worked for me is the following:

1) Clear all partitions off the harddisk.

2) Using FDISK from MS-DOS, create a "Primary DOS" partition that will
   be Your *only* DOS partition.

3) Create - using MS-DOS FDISK again - a "Secondary DOS" partition that
   will be used for BSD.

4) Using Norton's DISKEDIT or something similar, alter the byte indicating
   the partition type from 06 (Secondary/Extended DOS) to A5 (386BSD).
   (for the real hackers, edit absolute sector 0, changing the byte at
   offset 450/466/482/498 for partition 1/2/3/4).

5) The 386BSD 'install' program now recognizes the second partition as
   the 386BSD partition, and installs 386BSD there.

6) Use a DOS-based boot-partition switcher to replace the Master Boot
   record so You can select which partition to boot from as part of the
   booting proces. Several of these are avaiable at ftp archives such as
   wuarchive.wustl.edu / oak.oakland.edu / wsmr-simtel20-army.mil . If
   You cannot find one, I can e-mail or post one.
