AUTOSET Software

Boot PROM

(This option is for systems with an EXM-10A installed. The EPC-8 does not support

the boot PROM option of AUTOSET. Refer to the EXM-10A Hardware Reference

Manual for more information.)

Configuring Additional Ethernet Controllers

To configure multiple Ethernet controllers for use in a single EPC, each Ethernet

controller must be inserted in the computer and configured, one at a time, before

inserting the next Ethernet controller. EXM-10A Ethernet controllers are shipped

with the default I/O base address of 240h. A conflict occurs if more than one

unmodified Ethernet controller is installed at a time. If I/O base address 240h is not

available, disable the conflicting EXM and configure the Ethernet controller. To

install more than one Ethernet controller, follow these steps:

1. Turn the EPC off, install one Ethernet controller, and turn the EPC on.

2. Modify the EXM configuration data using the BIOS setup screen.

3. Invoke the AUTOSET program and select "Display/Change Configuration."

4. Manually select an available I/O base address.

5. Specify the other configuration options for this Ethernet controller.

6. Run Diagnostics to validate the configuration options.

7. Save the configuration, then exit the AUTOSET program.

Repeat this procedure until all Ethernet controllers are installed and configured. Make

sure that no parameter conflicts occur among the Ethernet controllers. With the

exception of the last Ethernet controller configured, each card must be set to an I/O

address other than 240h. That way, as each succeeding Ethernet controller is installed

with its factory default of 240h, no conflict occurs with preceding Ethernet controllers.

The software driver for each Ethernet controller must be configured to match that

Ethernet controller's actual IRQ and I/O base address.

A unique I/O address for each Ethernet controller is required so that AUTOSET can

distinguish which card is to configure. Two cards cannot share the same I/O base

address; if they do, neither will be configurable. If this occurs, remove one card and

change the I/O address on the one still in the system, then return the first card.

When using an EPC-8 with an EXM-10A installed, you cannot start AUTOSET while

already connected to the network. The system will have to be logged off.
