DRDOS sources are available at http://www.drdos.net/download.htm
It's been a very long time since I looked at them, so I don't recall
what all is there. I know the kernel is and I would expect the BIOS
sources to be as well.
Another DOS networking package you might find interesting is NCSA
Telnet. IIRC (and I probably don't) the DOS internetworking API was
pretty much invented by the folks doing NCSA telnet and copied by
everyone else.
An old article about how DOS internetworking works can be found over at
http://sunsite.uakom.sk/sunworldonli...nectivity.html
The google term you'll want to use to find more is "packet drivers" and
you might want to throw in a "wollongong".
Entirely off-topic, you might also be interested in the Contiki
operating system; see http://www.sics.se/contiki/ It's a very small
operating system that supports internetworking. IIRC (and I probably
don't) it started out on the Commodore 64.
