Here is my dosformat utility for Microport UNIX V/AT. The uuencoded
image files need to be decoded and placed in /usr/local/lib.
Enjoy!

X# dosfmt -- format a DOS floppy on Microport UNIX V/AT
X#
X# Dec. 18, 1988 by Wolf N. Paul
X#
X# This program may be freely copied and used for any purpose;
X# I would appreciate it if my name were retained, but have no way
X# of enforcing this.
X#
X# No warranties or promises are made regarding the performance
X# of this program; use at your own risk.
X#
X#
X# Usage: dosformat [#] [xx]
X# dosformat X:
X# Where: # is the drive number ( 0 = A:, 1 = B:)
X# xx is the disk type (DD = 360K, HD = 1.2M,
X# QD = 720K, XD = 1.44M)
X# X: is a DOS-style drive specification, i.e. A: or B:, etc.
X#
X# None of the options are case sensitive. If Drive Number is not given,
X# default is 0.
X# If Disk Type is not given, default is HD for Drive 0, and DD for
X# Drive 1.
X# If DOS-style drive spec is given, drive number and type are determined
X# from the entries in /dev/dos.
X#
X# Please note that 360K disks formatted in an AT-type drive will not always
X# work reliably in an XT-type drive.
X#
X# As written, this program assumes that you have entries for your
X# floppy disks as follows:
X#
X# /dev/rdsk/fd0dd 360K floppy installed as drive 0
X# /dev/rdsk/fd0hd 1.2M floppy installed as drive 0
X# /dev/rdsk/fd0qd 720K floppy installed as drive 0
X# /dev/rdsk/fd0xd 1.44M floppy installed as drive 0
X#
X# and alternately, the same names with a '1' instead of the '0' if you
X# have any of these installed as drive 1.
X#
X# Note that on Microport V/AT, floppies have more complicated names; you need
X# to make links with the above names to the appropriate Microport names.
X# I find these names easier to use than the default names.
X#
X# Note also that you can have multiple entries for the same physical drive;
X# for example, the standard AT drive 0 can have entries as fd0dd, fd0qd, and
X# fd0hd, to format to 360K, 720K, and 1.2 MB respectively.
X#
X# I have been successful in formatting normal DD diskettes to 720K; these should
X# be readable under DOS in an AT drive.
X#
X# If you wish to use the DOS-style drive specification (see usage message), you
X# also need links for each of your drives in /dev/dos. Microport recommends
X# /dev/dos/A for the AT drive 1, and /dev/dos/B for either drive 0, 360K on
X# a single drive system, or for drive 1, whatever, on dual-drive systems.
X# The Microport manual page for DOSDIR suggest that these should be links
X# to the fd* entries in /dev/dsk; however, for hard disk DOS partitions they
X# suggest that links be made to entries in /dev/rdsk. I suggest that /dev/rdsk
X# devices are more appropriate for the floppy entries, as well. Actually, the
X# Microport distribution disks have links in /dev/dos to the devices in
X# /dev/rdsk, so the manual probably is wrong.
X# Note that since these are in effect file names, you need to make similar
X# links with lower case names if you do not wish to use the shift key when
X# specifying the drive to the dos* utilities.
X#
X# The program works by formatting the disk with the Microport /etc/format
X# command, which does a low-level format, and then copying an image of track 1
X# of the appropriate DOS file system onto the disk. The DOS file system images
X# are stored in packed form; if your system has a faster or more efficient
X# compression program, you can unpack and recompress the image files, and change
X# the invocation of "pcat" towards the end of the program to whatever will
X# uncompress a file to the standard output on your system.
X#
X# Currently, I provide image files for HD and DD diskettes (dosfdimg_hd.z and
X# dosfdimg_dd.z); since I don't currently have 3.5" drives in my machine, I
X# could not conveniently produce the appropriate images for these disks. The
X# procedure to produce the images is simple:
X#
X# Format an appropriate disk using DOS, and then read the first track from that
X# disk using "dd" as follows:
X#
X# (Assuming a 1.44M 3.5" floppy (type XD)):
X#
X# dd if=/dev/rdsk/fd0xd of=/usr/local/lib/dosfdimg_xd bs=18k
X#
X# Then pack it (or compress using some other utility, see above):
X#
X# pack dosfdimg_xd
X#
X# This will produce a file dosfdimg_xd.z.
X#
X# If you wish to speed up the program, and have plenty of hard disk space,
X# you can of course store the image files uncompressed and change the
X# appropriate line towards the very end of this program.
X#
X# ERROR HANDLING:
X#
X# This refers specifically to the handling of bad sectors. If the first
X# attempt to format the disk fails, the format is repeated. If the first
X# attempt to write the DOS image fails, the format is also repeated. I have
X# noticed that this sometimes helps on Microport V/AT systems. If the
X# diskette still produces errors after the second format, it is rejected,
X# since UNIX cannot map bad sectors on a DOS disk. You may still be able
X# to use this disk on a DOS system, since DOS will simply map and not use
X# the bad sectors. I usually throw them away, since it is more hassle than
X# a disk is worth to try and keep them separate.
