I've just had a quick look at the os2warp.be site. The PCMCIA chipset 
page is, inadvertently, quite misleading. There should be a large caveat 
before the chipset/driver listing pointing out that, at least in the 
case of Cardbus NIC's, that no driver or socket services are required. 
The user should go to the NICPAK page FIRST and search for their PC 
card. For example, the Xircom Realport cards are listed in NICPAK.

I first reported this on the os2-warp list, probably 8 years ago!
