Figure 2-1 shows a functional block diagram of the Gigabit
Ethernet/82543 PMC Module. As the diagram shows, the key functional
components are the Intel 82543GC Ethernet LAN Controller, the Marvell
Alaska TM 88E1000 Gigabit Ethernet Transceiver chip, and serial
electrically erasable programmable read-only memory (EEPROM).

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.
