11. NETWORK OPERATION
11.1 Overview
The Ethernet interface on
MOPSlcd6
is realized with the 82559ER from Intel
, a fully integrated
10BASE-T/100BASE-TX LAN solution. The 82559ER consists of both the Media Access Controller
(MAC) and the physical layer (PHY) interface combined into a single component solution. The 32-bit
PCI controller provides enhanced scatter-gather bus mastering capabilities and enables the 82559ER
to perform high speed data transfers over the PCI bus. Two large transmit and receive FIFOs of 3
Kbyte each help prevent data underruns and overruns while waiting for bus accesses. The 82559ER
can operate in either full duplex or half duplex mode. In full duplex mode the 82559ER adheres with
the IEEE 802.3x Flow Control specification. Half duplex performance is enhanced by a proprietary
collision reduction mechanism. The 82559ER also includes an interface to a serial (4-pin) EEPROM.
The EEPROM provides power-on initialization for hardware and software configuration parameters.
The 82559ER provides following features:
•
Integrated IEEE 802.3 10BASE-T and 100BASE-TX compatible PHY
•
Glueless 32-bit PCI master interface
•
Improved dynamic transmit chaining with multiple priorities transmit queues
•
Backward compatible software to the 82558 and 82557
•
Full Duplex support at both 10 and 100Mbps
•
IEEE 802.3u Auto-Negotiation support
•
3 Kbyte transmit and 3 Kbyte receive FIFOs
•
Fast back-to-back transmission support with minimum interframe spacing
•
IEEE 802.3x 100BASE-TX Flow Control support
•
Adaptive Technology
•
TCP/UDP checksum offload capabilities
•
Low power 3.3 V device
•
Clockrun protocol support
11.2 Configuration 82559ER
Perform the following steps to configure your 82559ER PCI Ethernet Adapter:
1. Connect your network cable
The cable must be connected before loading the setup tool. To check the adapter's configuration run
the 82559ER DOS setup utility, named setup.exe, included in the driver archive.
The setup utility shows the adapters configuration:
Adaper type:
Currently selected adapter.
Adapter part number:
Part number of the adapter.
Network address:
Node (MAC) address of adapter in hexadecimal.
Interrupt:
The interrupt the PCI BIOS assigned to the adapter.
Bus:
PCI bus number slot ID of the adapter.
Slot:
Slot number used for the adapter drivers.
Device:
Device number assigned by the PCI BIOS.
Network speed:
Speed of the current network link.
Physical layer device:
Actice physical layer device.
Duplex:
Current duplex setting.
Adapter capabilities:
Link type supported by this adapter.
2. Perform diagnostic tests „Test adapter“ in main menu if needed.
