8.When prompted as to whether you want to save the current code to a diskette, select N.
9.When prompted to choose a language, select a language (from 0 to 7) and press Enter to accept your choice.
10.Do not reboot your system at this time.
11.Remove the BIOS Flash Diskette from the diskette drive.
12.Turn the server off.

Troubleshooting the Ethernet controller
This section provides troubleshooting information for problems that might occur with the 10/100 Mbps Ethernet controller:
Network connection problems
If the Ethernet controller cannot connect to the network, check the following:
•Make sure that the cable is installed correctly.
The network cable must be securely attached at all connections. If the cable is attached but the problem persists, try a different cable.
If you set the Ethernet controller to operate at 100 Mbps, you must use Category 5 cabling.
If you directly connect two workstations (without a hub), or if you are not using a hub with X ports, use a crossover cable.
Note: To determine whether a hub has an X port, check the port label. If the label contains an X, the hub has an X port.
•Determine if the hub supports
•Check the LAN activity light on the front of the server. The LAN activity light illuminates when the Ethernet controller sends or receives data over the Ethernet Network. If the LAN activity light is off, make sure that the hub and network are operating and that the correct device drivers are loaded.
•Make sure that you are using the correct device drivers, supplied with the server.
•Check for operating
•Make sure that the device drivers on the client and server are using the same protocol.
•Test the Ethernet controller:
How you test the Ethernet controller depends on which operating system you are using (see the Ethernet controller device driver README file).
