Board Installation
adapter have the same duplex setting. If you configured the adapter for
full duplex, make sure the hub port is also configured for full duplex.
Setting the wrong duplex mode can degrade performance, cause data loss,
or result in lost connections.
Testing the adapter
Test the adapter by running Intel diagnostics. For DOS or Windows 3.1
computers, run Setup on the Intel Drivers and Configuration disk. For Win-
dows NT and Windows 95 run Intel PROSet by double-clicking the Intel
PROSet Icon in the Control Panel. Click Help from the main PROSet window to
get complete diagnostics information and instructions.
Common problems and solutions
SETUP.EXE reports the adapter is Not enabled by BIOS.
The PCI BIOS isnt configuring the adapter correctly.
The computer hangs when the drivers are loaded.
Change the PCI BIOS interrupt settings.
If you are using EMM386, it must be version 4.49 or newer (this version
ships with MS-DOS 6.22 or newer).
Diagnostics pass, but the connection fails or errors occur.
At 100 Mbps use category 5 wiring and make sure the network cable is
securely attached.
For NetWare clients, make sure you specify the correct frame type in our
NET.CFG file.
Make sure the duplex mode setting on the adapter matches the setting on
the hub.
At 100 Mbps, connect to a 100BASE-TX hub only (not T4).
The LNK LED doesnt light.
Make sure youve loaded the network drivers.
Check all connections at the adapter and the hub.
Try another port on the hub.
Make sure the duplex mode setting on the adapter matches the setting on
the hub.
Make sure you have the correct type of cable between the adapter and the
hub. 100 BASE-TX requires two pairs. Some hubs require a crossover cable
while others require a straight-through cable. See the Cabling README file
for more information on cabling.
