NT Configuration problems
-------------------------

For detailed information on working configurations for
platforms running Windows NT 4.0, see the file
NTConfg.txt in the \Help directory on the Installation
CD.

Toshiba Topic 97-based Controller Notebooks
-------------------------------------------
For Toshiba Topic 97-based controller notebooks 
using the Pentium II processor and running
Windows 98 or Windows 95 OSR 2, setting the
PC Card controller to Auto Mode may optimize 
performance. 

To determine if you have a Topic 97:
1. Using the Control Panel, click the System icon.
2. Click Device Manager and then click PCMCIA Socket.
3. Topic 97 will be listed as the controller.
Check with your notebook vendor for more information.

Docking Station or Port Replicator
---------------------------------- 
Some notebook docking stations do not 
properly manage resources for the CardBus PC Cards. 
If you notice this problem, we recommend that you 
install the CardBus PC Card in the CardBus PC Card 
slot in the notebook itself and not in the PC Card 
slot in the docking station or port replicator.

Pre-Pentium II Toshiba Notebooks
--------------------------------
For Pre-Pentium II Toshiba notebooks, set the BIOS to 
CardBus mode as described in the User Guide.
Check with your notebook vendor for procedures 
for setting CardBus mode on other models.

Duplex Operation
----------------
The 3Com network drivers support full-duplex operation 
(sending and receiving data simultaneously).  

WARNING: 
You MUST be connected to a full-duplex, Nway, 
auto-negotiating Ethernet switch set to auto-negotiating mode
to use this feature. To enable this feature, see the User Guide.

BIOS Information
----------------
Make sure to use the latest BIOS available 
for your notebook. Contact the notebook manufacturer 
for more information.

Network Link and Full Duplex Selection
--------------------------------------
When you select the Network Link Selection in the Network 
Properties window, this new value overrides the duplex
setting in the EEPROM, which can be set with the DOS 
diagnostics.

To connect to a 10 Full Duplex switch port, use the
10FULLDUPLEX keyword in the NET.CFG file. Do not
change the default "Auto Negotiation" value with
the DOS Diagnostics.
