I recently installed a second NIC in my file server (Gentoo Linux 2.6.15-r1). The first network card works fine and comes up in lspci accurately. (Ethernet controller: D-Link System Inc (Gigabit Ethernet Adapter (rev 11)) The second identical card (DGE-530T) comes up in lspci as D-Link System Inc Unknown Device 4b01 (rev 11).
I'm pretty sure that this is just a resource conflict, but I don't know how to go about fixing it in Gentoo. (bit of a newbie.) Any help will be appreciated.
