for a label that has a barcode and a number in the format
of 123456-001 (six digits hyphen 3 digits).

Determining Your Adapter's Hardware
(MAC) Address WW
Note: This is not yet
proven and may very well be wrong.
At the top of the adapter (see "Enet Addrs" text in
outline) is printed the text "Ethernet Address". Along
with the text there is a set of six numbers and "x"
characters with an arrow pointing down to U1's outline.
I believe this means that the set of numbers printed on
the adapter card is permanent, as the numbers take this
I think the "x" digits are to be replaced by the
numbers printed on the IC at U1, therefore (in the case
of my adapter):
00AA003A4203 (there's an $ after this, but that isn't a
valid MAC address character!)
Chipset-wise this adapter is built around
some of the same components as the 3Com 3C523(TP). The
3Com card is a decent performer and can give you close to
the best possible results from a 10Mbit Ethernet line. It
will do this without totally flooring the CPU.
I would expect that this Intel adapter offers about the
same performance. Alfred Arnold did some speed testing
on this and a few other MCA Ethernet cards. You can find
the results here and it does look like the 3C523 and
EtherExpress are close.
Configuration Required LFO
Automatic configuration works, EXCEPT when:
Installing more than one EtherExpress in a system.Install
boards one at a time and set IRQs.
RPL / BOOT ROM Flash Memory address and BOOT ROM type must
be selected manually
Enable Flash Memory - either for BOOT ROM or any other
At this time, I am unsure if the EtherExpress
MCA is considered a "Flash" adapter and are supported by
the Intel network management software for Flash based
adapters. Might be....

NOTE: This version
[1.01] separates the options for the RJ-45 and BNC
connectors into two selections. The previous version
combined these two connectors into one selection, causing
a problem accessing the RJ-45 connector with the WindowsNT

I/O Address Range
Each EtherExpress requires a range of I/O
addresses that doesn't overlap those used by any
other adapter. If an an asterisk appears to
the right of the field, the range you have selected is
being used by another adapter and you will have to
choose a different range. If you want a more detailed
explanation, refer to 'I/O address' in the index of the
Complete Guide to Installing."

The EtherExpress adapter needs to be
assigned a unique hardware IRQ. Although Micro
Channel systems allow devices to share IRQs, network
performance would suffer if the network adapter used the
same IRQ as another device. If the serial port on the
motherboard is set to COM1, it uses IRQ 4. Any
other serial port in your system should use IRQ 3.
Various other adapters may also use one of the IRQs
available to the EtherExpress adapter. To verify
that you have not set your EtherExpress adapter to the
same IRQ as another device in your computer, run
the program MCADIAGS, on the EtherExpress diskette.

Flash/Boot ROM Address Range
The Micro Channel EtherExpress
adapter has 256k of FLASH RAM on board. This can
provide Boot ROM capabilities, it can be used with
optional software for various utility purposes, or it
can do both. To allow the use of the FLASH RAM,
either for utility purposes or as a Boot ROM, an 8k
address range must be assigned. If a selection
causes an asterisk (*) to appear, it is conflict another
device's memory address and the FLASH/Boot ROM address
must be changed.

Boot ROM Options
For a Boot ROM to be enabled, you must
assign an address range in the FLASH/Boot ROM choice
field above. The EtherExpress adapter Boot ROM
feature allows the workstation to be booted from a
'boot image' stored on the network server. Novell
Netware and Microsoft LANMAN are supported. If you
do not intend to boot this workstation from the network,
choose 'Boot ROM Disabled'."

The EtherExpress board can automatically
detect which connector has a cable attached. For most
uses choose 'Auto detect.'
If you need to override the auto-detect feature,
choose the connector type you plan to use.

Network Driver Information
Information on installing the drivers
for various network operating systems is available in
README files on the EtherExpress option diskette.
Boot the system to DOS, put the EtherExpress option
diskette in a floppy drive, switch to that drive and run
MCADIAGS. More information on network driver
installation is available from our FaxBack(tm) service
or on our BBS. Refer to the EtherExpress manual
for more details."
