Appendix H: AUTOSET Software

87

For a single Ethernet controller installation, follow these steps:

1.

From the AUTOSET program, select “Display/Change Adapter Settings” to set up the
Ethernet controller just installed.

2.

Skip the Novell Configuration prompt. It does not apply to the EPC-8A.

3.

Select the I/O base address. Use the tab key to change the Ethernet controller's I/O
base address to any available location.

300h is recommended because it allows the use of most network software
drivers without modification or configuration.

4.

Select the Interrupt Assignment. Be sure to avoid any interrupts used by other
interfaces in the system.

5.

Select the Physical Media cabled up: only 10BASE-T is available for the EPC-8A.

6.

Select the Adapter architecture. Use “I/O Port” for NE2000 mode, or use “Shared
Memory” for Western Digital mode.

7.

Skip the Boot PROM prompt. It does not apply to the EPC-8A.

8.

Save the configuration to the on-board memory only if your system is currently not
connected to the network. If you are experiencing difficulties, save as temporary
changes to determine if they work correctly, then run AUTOSET again and save the
changes as permanent.

9.

Run Diagnostics to verify the setup. If using Western Digital mode, specify a shared
memory base address to be used during diagnostics. Also, to guard against conflicts,
exit Diagnostics and check that any EMM386 entries in the CONFIG.SYS file and
SYSTEM.INI file (if using Windows) both exclude the memory assignment to the
Ethernet controller. The default memory exclusion range is DC00–EFFF. If the system
does not pass the Diagnostics, try again, changing the indicated parameters.

10. Press ESC to return to the previous menu.

If only one Ethernet controller is to be installed, the configuration procedure is complete.
Exit the AUTOSET program and turn to Appendix K, Configuring the Ethernet Drivers.

The responses entered from the AUTOSET configuration menu depicted in the previous
figure are discussed in detail below.

Novell Configuration

There are several pre-set Novell Configuration options programmed into the AUTOSET
program that are not applicable to the EPC-8A. The Novell Configuration option must be
set to None.

I/O Base Address

The Ethernet controller uses 32 bytes in I/O space. The I/O Base Address must be selected
using the AUTOSET program. The AUTOSET program can only access the Ethernet
controller when the I/O space occupied by the Ethernet controller does not conflict with I/
O space previously assigned. In addition, the network interface drivers used with the
