Booteasy handled multiple disks OK on my box.  However, it daisy-chains the
slices for the second disk as another menu off the initial menu for the
first disk.

This, plus other things I didn't like about the booteasy menus led me to go
with OS/BS 2.0B8.  Much nicer interface: 1 menu, color, digit or arrow key
selection, timeout freeze, supports multiple disks, it'll even let me boot
off my SCSI ZIP drive when I've got my SDMS BIOS enabled.  Boots my DOS/95
partitions off Disk 0 and FreeBSD (and a while back Linux) off Drive 1.

 |heads, and the BIOS only allows up to 15.  As osbs20b8 installs through
 |DOS, and writes to more than the first sector, this causes problems....

Right.  DOS always starts its partition at Track 0 Head 1, leaving Track 0
Head 0 empty.  OS/BS needs more than just sector 1 (MBR) at the front of
the disk.  It additionally uses sectors 2-5 on Track 0 Head 0, presuming
based on DOS's layout that this space will be available.

   disk. That is, leave the space from Cylinder 0, Head 0, Sector 2
   through Cylinder 0, Head 0, Sector 63 unallocated, and start your
   first partition at Cylinder 0, Head 1, Sector 1. For what it's worth,

Easiest way to avoid trouble here is to skip Track 0 Head 0 when creating
FreeBSD partitions, and start them on Track 0 Head 1.  If you already have
a DOS partition on your disk up-front, you don't need to deal with this.
