Troubleshooting

❑ If you are using EMM386.EXE, verify that you have version

4.49 or higher. Lower versions of EMM386 can cause a PCI

machine to lock up or reboot. Version 4.49 ships with DOS

6.22 and is available on the Microsoft forum on

CompuServe.

❑ If you suspect the network adapter card is not working

properly, disconnect the computer from the network and

run CardAssistant diagnostics after rebooting with no

drivers loaded.

❑ If CardAssistant software does not detect the card, it could

mean a conflict between the card and another device, a card

failure, or a slot failure. Try installing the AT-2450 in

another computer. You may need to reconfigure the other

device to avoid the conflict.

❑ If the card passes diagnostics, try reconnecting the

computer to the network. A failure may be caused by

physical medium connections or by corrupted network

software. You can test the connectors, terminators, and

cables by swapping them for known good ones.

❑ Replace corrupted network software.

Manual/Adapter Card/CardAssistant/Driver Compatibility

This manual is intended for use only with the AT-2450 PCI

Ethernet Adapter Card 8-interrupt jumperless adapter cards

with which it was shipped. The manual will incorrectly reflect the

use of earlier adapter cards.

The Release 3 CardAssistant software and card drivers shipped

with this manual are backward-compatible with respect to the

AT-2450 PCI Ethernet Adapter Card, and will operate correctly

with earlier versions of the card.
