I'm wondering if the internal modem is a serial device working through a UART on the board, or if it is on an ISA(possibly PCI) bus, like a normal internal modem. If the later is the case, it should only be a matter of a little solder work to get a normal ethernet NIC in there.
Internal modem on ISA or serial? (Score:2)
If the later is the case, it should only be a matter of a little solder work to get a normal ethernet NIC in there.
