Configuring the 100/10 PCI Ethernet Adapter

Troubleshooting

ŸMake sure that you are using the drivers that come with this adapter.

ŸMake sure that the driver is loaded and the protocols are bound. See the Network Bindings dialog box in Windows NT Server 3.51 to verify this.

ŸMake sure that you are using Category 5 cabling when operating at 100 Mbps.

ŸTest the adapter using the instructions in “Configuring for Windows NT Server 3.51” on page 68.

ŸCheck with your LAN administrator.

Configuring for Other Operating Systems

Refer to the help files on the Ethernet Configuration and Drivers program for instructions on configuring for other operating systems.

To view the help files, insert the Ethernet Configuration and Drivers diskette in drive A, and switch to that drive. At the operating-system prompt, type SETUP \README. Then, press Enter.

Select Installing 100/10 PCI Ethernet adapter drivers.

Duplexing

Duplexing is a performance option that lets you choose how the adapter sends and receives packets over the network.

There are three duplex modes:

Full duplex The adapter sends and receives packets at the same time, increasing adapter performance. This mode requires a full-duplex hub.

Half duplex The adapter performs one operation at a time: it

either sends or receives packets.

Auto-negotiateThe adapter negotiates with the hub on how to send and receive packets, through either full or half duplex mode.
