This software program, ETHERCHX.EXE, tests GATEWAYS G/Ether PC, AT, MC, and
AT HUB cards for correct settings, properly operating hardware, and error-free
memory. In order to run this diagnostic, you need the following:
ANSI.SYS must be installed, in order for some of the messages be to
properly displayed.
(1) You must know the base I/O address, Boot PROM address, and IRQ selection
used for this adapter card. If you do not know these settings, then
remove the G/Ether card from your PC, run these instructions again,
record the settings, turn off the PC, re-install the adapter card,
restart the PC and again follow the instructions given in the diagnostic.
(2) The adapter card to be tested must be installed in the correct computer.
(3) If you have a connection to an G/Ether network, it must be quiet. (no
traffic) Or you may disconnect the network connector without affecting
the test. (G/Ethernet controllers require a connection to a network,
AT HUB cards do not need to be connected, but may.)
(4) Configuration information which is identified as follows:
(a) DEVICE I/O ADDRESS is set by switches 1, 2, 3 and 4 of SW1:
Device I/O Address Switches on SW1
Active Range (hex) 1 2 3 4
----------------------------------------------------------
1. 00280 - 0029F ON ON ON ON
2. 002A0 - 002BF ON OFF ON ON
3. 002C0 - 002DF ON ON OFF ON
4. 002E0 - 002FF ON OFF OFF ON
5. 00300 - 0031F ON ON ON OFF
6. 00320 - 0033F ON OFF ON OFF
7. 00340 - 0035F ON ON OFF OFF
8. 00360 - 0037F ON OFF OFF OFF
(b) IRQ (INTERRUPT REQUEST LINE) is set by JP2:
PC Card
Interrupt Jumpered
Selected Pins on JP2
--------------------------------
1. NONE NONE (not valid for this test and most software)
2. IRQ2 1 & 2
3. IRQ3 3 & 4
4. IRQ4 5 & 6
5. IRQ5 7 & 8
6. IRQ6 9 & 10
7. IRQ7 11 & 12
AT Card
Interrupt Jumpered
Selected Pins on JP2
--------------------------------------
3. IRQ3 3 left & 3 right
4. IRQ4 4 left & 4 right
5. IRQ5 5 left & 5 right
6. IRQ6 6 left & 6 right
7. IRQ7 7 left & 7 right
9. IRQ9 9 left & 9 right
10. IRQ10 10 left & 10 right
11. IRQ11 11 left & 11 right
12. IRQ12 12 left & 12 right
15. IRQ15 15 left & 15 right
(c) AUTOBOOT PROM ADDRESS RANGE is set by switches 5 and 6 of SW1:
Autoboot PROM Switches on SW1
Address Range (hex) 5 6
---------------------------------------------
1. NONE
2. C0000 - C3FFF ON ON
3. C4000 - C7FFF OFF ON
4. C8000 - CBFFF ON OFF
5. CC000 - CFFFF OFF OFF
The diagnostic requires that the adapter card is installed in the PC. When
you are ready to run the diagnostic, execute "ETHERCHX".
Appendix A. How to interpret the AT HUB status report
The AT HUB status report is divided into three main sections each occupying a
line of the display.
The first information line pertains to the AT HUB card itself.
The second information line pertains to expansion card #1.
The third information line pertains to expansion card #2.
Information about the expansion cards will be displayed even if the cards
are not installed.
Each status line shows the state of the jabber (JAB) and link (LNK) lamps
for each of the four ports on each card.
To test the jabber circuitry, depress the asterisk (*) key on the PC keyboard
and observe ALL ports display an ON condition for approximately two seconds.
While observing the indicator lamps on the card, depress the asterisk (*) key
on the PC keyboard again and observe ALL port indicators display an
illuminated condition for approximately two seconds.
To test the link circuitry move any RJ45 connector to a new plug. The link
lamp associated with the "from" plug should extinguish as should the CRT
display change from ON to OFF. The link lamp associated with the "to" plug
should illuminate as should the CRT display change from OFF to ON.
