3C509 - How do I load Packet Drivers for two cards on one machine?

Question: I have two 3C509's in one machine. I can set different values for IRQ and I/O base addresses, but I cannot load two drivers. Why?

Answer: Install one adapter at I/O Base 300 hex and the other at 320 hex. To use the card located at 300 hex and load it at Ssoftware Vector Interrupt 60 hex use the command line:

3C5X9PD -w 0x60 IOBASE=0x300

To load the second Packet Driver use the command line:

3C5X9PD -w 0x69 IOBASE=0x320

Noote: Valid Software Vector Interrupts range from 60-80
