SYMPTOMS
========

When you are using Windows 95 on a computer with a DATABOOk PCMCIA controller
and two network adapters installed, Windows 95 may stop responding (hang) when
you start the computer or "hot swap" the network adapters.

CAUSE
=====

The DATABOOK PCMCIA controller does not handle bus contention on its card slots
properly when two network adapters are installed and network traffic is high.


RESOLUTION
==========

The first network adapter's lites must go out to enumerate the second device off
the controller. This may not happen on a busy network. If the lites do not go
out, remove the second apapter to prevent Windows 95 from hanging.

NOTE: Do not unplug the cable, as you might not be able to re-establish the
connection when you plug the cable back in.

Contact DATABOOK for more information.

MORE INFORMATION
================

According to DATABOOK, when you insert two network adapters into the PCMCIA
slots, the first adapter is initialized by the controller and activated, but you
cannot insert the second adapter until the first adapter's lights go out. On a
busy network where the first adapter is constantly in use, the controller may
hang when you insert the second adapter, causing Windows 95 to hang when you
start Windows 95 or when you "hot swap" a network adapter.
