NE2000 and NE2000+ users should select the I/O Port mode.
WD8003 and WD8013 users should select the Shared Memory mode.
Systems with limited amounts of memory should select I/O Port mode to avoid conflicts
with other memory-mapped devices.
Systems with ample memory, where increased performance is important, should select
Shared Memory mode.
Boot PROM
(This option is for systems with an EXM-10A installed. The EPC-8A does not support the
boot PROM option of AUTOSET. For more information, refer to the EXM-10A Hardware
Reference Manual.)
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 are 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-8A with an EXM-10A installed, you cannot start AUTOSET while
already connected to the network. The system must be logged off.
