Does anyone know a trick to get dual-boot working on a machine
with an IDE drive that is greater than 528MB?

DOS has a limit of 1024 cylinders and most utilities
translate the extra cylinders into heads.  BSD/OS has only a
4-bit field for the number of heads which make 16 heads
the max.  It seems that I can't get a consistent view of
the disk to make dual-booting possible.  I think I had
tried all choices (BIOS, CMOS, FDISK, etc) on version 2.1
installation process without success.


Any help will be appreciated.
