I'm trying to figure out what mini PCI cards (for the T4x platform) would work well with OS/2--or really ArcaOS. Sort of thinking out loud.
What is in it? Use PCI.EXE to find out. I think most, of the T4x line has network drivers. Personally, I wouldn't bother trying to replace whatever is in it. You would be better off to get an external WiFi adapter, that connects to the wired NIC. They are usually handy for other things as well.
