i have 2 p-III machines which have one lan card installed to connect to the network. since there is only one i/o box in my room i can only connect one machine at a time. i heard that xp support 2 lan cards so to save cost i installed 2 cards on a machine running xp pro. >dlink and a compex card both based on RTL8129/8139 Chipset. winxp automatically detects one of the card connected on pci-1 but does not detect the other. how do i make both of them work on a single machine. and if they work how do i configure them so that both the comps connect to the network .
