I've installed IBM OS/2 v1.2 on a 386 clone and am having some problems
with booting DOS from a floppy (otherwise it works fine).

Several weeks ago, several messages described a procedure to set up
OS/2 1.2 so that dual boot and HPFS could co-exist.  The main point of
these messages was that DOS won't recognize the HPFS c:  partition and
so will be "fooled" into thinking that a d: FAT partition is c:.

I don't plan on using dual boot much, so I arranged, as was described
in one of those messages, to boot DOS from a floppy.  The advantage was
that one would not have to use FDISK to switch the primary partition on
the hard disk before booting the other system.  I installed OS/2 with
HPFS on the c: drive, and made a small FAT d: drive on which I planned
to install whatever DOS software I had that wouldn't work in the 
compatibility box.

Either this procedure doesn't work or I executed it incorrectly.  DOS
doesn't recognize any partition at all on the hard disk when booted
from a floppy.  This makes some sense WRT a recent article in Byte
about HPFS, as by formatting c: with HPFS, the extended partition
information is also lost, so DOS can't find the extended partitions,
regardless of whether or not they are FAT.

Can anyone enlighten me as to what I should do, what steps I omitted,
or why what I want to do can't possibly work?

Thanks in advance.
