Appendix E On-Board Ethernet

The Raptor AT features a built-in 10/100 Ethernet controller (82559ER).

The 89559ER is a 32-bit PCI controller that features enhanced scatter- gather bus mastering capabilities which enable the 82559ER to perform high-speed data transfers over the PCI bus. The 82559ER bus master capabilities enable the component to process high-level commands and to perform multiple operations, thereby off-loading communication tasks from the system CPU.

It can operate in either full duplex or half duplex mode. In full duplex mode it adheres to the IEEE 802.3x Flow Control specification. Half duplex performance is enhanced by a proprietary collision reduction mechanism.

It can be enabled or disabled through jumper JP12.

The Ethernet Header connector pin-out can be seen on Table A-11.
