Intel 82543GC Ethernet LAN Controller
The Intel 82543GC Ethernet LAN Controller is a PCI bus controller that
supports IEEE 802.3 10 Mb/s, IEEE 802.3u 100 Mb/s, and IEEE 802.3z
and 802.3ab 1000 Mb/s data transfer rates. The controller is capable of
operating at bus speeds of 33 or 66 MHz, using bus widths of 32 or 64 bits.
