Mdir and friends as supplied with Esix expect /dev/rdsk/0s5 to be the dos
partition.  If the DOS "fdisk" programs shows partition 3 on your first hard
disk to be your DOS partition, you should be okay.  You may have to "su" and
change owner and/or permissions on the device (Esix creates them with mode
0600, owner root).

A better idea is to get the source to the whole mtools package via anonymous
ftp to cerl.cecer.army.mil (129.229.1.101).  If you try this, beware the broken
ftp server at that site (it likes to silently truncate files).  You have to
manually check that the files you receive are the correct size.  Trying a
second time usually works.

Once you have the source code, edit "devices.c" and define which DOS device
letters you want to be which unix devices.  I don't know if the mtools programs
correctly handle extended partitions.

If anyone is interested, I wrote a "packdisk" utility which lets you write a
bunch of files to one or more DOS diskettes, packing each diskette as
efficiently as possible.   It's written in perl, and requires you have the
mtools package source code.  Send email if you want a copy.
