ETHERNET CARD SETUP
For each NIC-2000 or NIC-1000 Ethernet card there are two parameters which
you will need to supply, the Interrupt Vector Number and Base I/O Address.
They must match the board configuration. Interrupt must be unlatched.
Be sure the interrupt vector you select does not conflict with other device
interrupt vector.
If you wish to go back and reconfigure your board or read the documentation
answer "no" to the next question.
