AIX 3.2.5 Documentation

I'm looking for books or online documentation for writing device drivers for AIX 3.2.5. I've searched IBM's website and google and come up with next to nothing. There is plenty of information for 4.1 and above but virtually nothing for 3.2.5.

I'm specifically interested in porting one of the open source 802.11b PCMCIA drivers to AIX 3.2.5 for use in my N40 (ancient laptop that will ONLY run AIX 3.2.5)

i dunt think so there is an accurate Online Documentation link for AIX but i suggest you to visit this site. (Actually its a book), It also covers the programmers manual for writting device driver also.

Excellent link! Heres to old books still in print! I dont think I'm going to find this one on the discount rack though. This should get me started, at least enough to determine if its feasable. Thanks.
