I have a PDF file for one particular mouse (guess it's compatible with that
of m$) on my site in "misc docs" section among a lot of different docs.
If you're ready to modify an existing mouse driver for DOS or write your
own, you're welcome.
One thing I want to say... My own code for PS/2 mouse seems to be working,
but something is still incorrect even though I seem to do right steps. I
mean, I can install an ISR on IRQ12, enable mouse and read X/Y/B off the
mouse but I can not uninstall it. It hangs the computer (or probably
keyboard) if I move a mouse afterwards. I do disable the mouse according to
that doc, but it doesn't really work.. Try to see if you can read wheel info
by using BIOS services (yes, BIOSes on computers equipped with PS/2 stuff
quite often (if not always) have support for a PS/2 mouse -- see int 15h in
Ralf Brown's Int List). Perhaps this is a way to go.

Good Luck
