@628B.ADF - Intel EtherExpress MC Network Adapter

Determining Model:
   On the lower left corner of the adapter, look for a label that has a barcode and a number in the format of 123456-001 (six digits hyphen 3 digits).

TX Light (yellow)

Status

Interpretation

On

Transmitting Constantly

EtherExpress is constantly transmitting. Could cause network problems if condition persists.

Blinks

Transmitting data

Normal. TX light only blinks when transmitting data.

Off

Not transmitting data

Normal.

RX Light (yellow)

On

Receiving constantly

Indicates very high level traffic on network.

Blinks

Receiving data

Normal. RX light blinks when receiving data. Should always be blinking when attached to network.

Off

Not receiving data

Card not receiving data, may be problem on network. Check Link Integrity Light.

Link Integrity Light (green)

On

Link Integrity good

Normal (RJ45 only)

Off

Link lost

No link to hub. Bad cable, connector, problem at hub (RJ45 only)

Polarity Light (red)

On

Polarity reversed

Polarity on RJ45 cable reversed. Adapter will automatically correct for this, but light will remain on until polarity is corrected.

Off

Polarity correct

Normal.



Difficult to Insert or Remove RJ45 cable LFO
  The retention clip on the AUI port may be in the up position, and over the bottom edge of the RJ45 port. Click the AUI retainer down.

Error 3095 and 3096 with EtherExpress MCA & MCA/TP under NT LFO
   An EtherExpress  adapter with RJ45 does not work with Windows NT. You do not get the network connection. The link light (L) is off. Old ADF combined sections for RJ45 and BNC connectors. Update to the 1.01 ADF.

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 form:

         00AA00xxxxxx

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!)


Thoughts  WW
   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.


Manual 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 purpose.

  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....


ADF Sections AdapterID 628B "Intel EtherExpress(tm) MC Network Adapter"  LFO
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 driver.
NOTE:  new version of ADF file only offers I/O mapping 7/28/92

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."
     <"x300h - x30Fh">, x310 - x31F, x320 - x32F, x330 - x33F, x340 - x34F, x350 - x35F, x360 - x36F, x370 - x37F, x200 - x20F, x210 - x21F, x220 - x22Fh, x230h - x23Fh, x240h - x24Fh, x250h - x25Fh, x260h - x26Fh, x270h - x27Fh

IRQ
    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.

  <"IRQ 11">, 10, 5, 9, 3, 15, 12, 4

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.
   <"Flash/Boot ROM Disabled">, D000-D1FF, D200-D3FF, D400-D5FF, D600-D7FF, D800-D9FF, DA00-DBFF, DC00-DDFF, DE00-DFFF, C800-C9FF, CA00-CBFF, CC00-CDFF, CE00-CFFF

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'."
    <"Boot ROM Disabled">, Novell Boot ROM, LANMAN Boot ROM

Connector Type
   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.
    <BNC>, RJ-45, AUI, Auto detect

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."
