Hi Ali,
I might slit my wrists … but seriously is this documented somewhere. I know how to write W2K and Linux, but not DOS driver.

It is so easy. There are numerous books.
Do you have access to Borland C++ 3.x? If so, I have a very nice DOS
framework I wrote to allow you to write DOS device drivers in C. I do
not recommend using much of the C runtime library as it loads lots of
unneeded stuff.
What I did was rewrite C0.ASM so that it reflects a “device driver
model”; synonymous with the way there are different C0.ASM files for the
different memory models; tiny, small, medium, large and huge.
I even added support so that you can drop initialization code after init
by putting it in its own section and placing it at the bottom of the EXE
file. I simply set the memory allocation size for the driver to be the
size of the driver minus the address of the “_FENCE” section. Using a
#pragma, you can put your initialization routines in the _FENCE section
so they get dropped.
It produces very tight drivers. If you are interested - if anyone is
interested - I can send you the framework that includes a driver I wrote
using it.
It even allow you to place a main() in the fenced init section that will
allow the .EXE to be run from the command line so that you can use the
same EXE file to control the device.
I did this many years ago, but I think I know where I put the code

In the dark DOS ages the only good source of information was Ralf Brown’s
Interrupt List: http://www-2.cs.cmu.edu/afs/cs/user/ralf/pub/WWW/files.html.
Now google can help; there were some books about this topic (seach for
“undocumented DOS”, “secret DOS” etc.). Also, there probably is a lot of TSR
(terminated and stay resident) programs with sources available – depending
what you need to do TSR can be better choice. Finally, there was Open DOS
from Caldera (?) with sources available.

One of my favorite DOS books was “The Waite Groups MS-DOS Developers Guide”.
It has chapters on drivers and TSR’s. Not sure where you could find it
though. Undocumented DOS by Shulman might be helpful as well.

In addition to all the other sources people have mentioned, there’s
Robert Lai’s “Writing MS-DOS Device Drivers” (Addison-Wesley 2d ed
1992). I’m sure this is out of print, but maybe you could find a used
copy somewhere. I can’t vouch for this book – I picked up a copy years
ago just because it was about drivers and I figured I might need it
someday, but I never (thank goodness!) needed to use it.
