J4 – Ethernet Connector

The Ethernet chip is the National Semiconductor DP83815 MacPhyter chip. It is connected to the ZfX86 CPU via the board’s internal PCI bus. It resides at address 1000 and uses IRQ 10.

The Prometheus Software CD includes Ethernet drivers for Windows 95, Windows 98, Windows NT, and Linux. The latest drivers can also be downloaded from National Semiconductor’s website at www.national.com. Search for DP83815 to reach the product folder.

A DOS utility program is also provided for testing the chip and accessing the configuration EEPROM. Each board is factory-configured for a unique MAC address using this program. To run the program, you must boot the computer to DOS. The program will not run properly in a DOS window inside of Windows. In normal operation this program should not be required.
