"2Wire seemed to be rather obscure when I obtained the pccard.... but DriverGuide to the Rescue! It worked well, both on a laptop, and a desktop... both running xp. The desktop installation and operation was a little hinky, but I attributed that to the cheap PcCard reader PCI expansion card I obtained."
