SYMPTOMS
========

When you try to use the Marconi/Fore PCA ForeRunner ATM network adapter in your
Windows NT-based, multiple-processor computer, your computer may stop responding
(hang). Note that this issue does not occur if you are using only one central
processing unit (CPU).

CAUSE
=====

This issue can occur if you are using a version of the ForeRunner ATM PCI
network adapter driver (Foreatm.sys) that is earlier than version 5.1.0.49979.

RESOLUTION
==========

To resolve this issue, contact Marconi to obtain a version of the ForeRunner ATM
PCI network adapter driver (Foreatm.sys) that is later than version
5.1.0.49979.

To work around this issue, use the appropriate switch in the Boot.ini file to
limit your computer to a single CPU:

- /numproc=1

- /onecpu (only for use with Compaq computers)
