There's a great deal of inportant information in a couple of the "red
books":  "OS/2 2.0 Technical Library, Virtual Device Driver Reference"
and "OS/2 Version 2.0, Volume 2: DOS and Windows Environment".

You can buy the red books direct from IBM, or you can order a copy of
the Professional Developers Kit (PDK) CD-ROM, which contains these
documents as well as a *wealth* of other information.  ( Best excuse
for a CD-ROM drive I know! :)

Best regards,
John
