resource settings for the board.

The network controller requires drivers.

Verify that the drivers were not accidentally deleted when the

drivers for a new expansion board were installed.

The expansion board installed is a network card (NIC) and

conflicts with the embedded NIC.

Under the Computer Setup

Advanced

menu, change the

resource settings for the board.

Network controller stops working without apparent cause.

Cause

Solution

The files containing the network drivers are corrupted.

Reinstall the network drivers, using the Recovery Disc Set

created from the hard drive's Recovery Partition.

The cable is not securely connected.

Ensure that the cable is securely attached to the network

connector and that the other end of the cable is securely

attached to the correct device.

The network controller is defective.

Contact an authorized service provider.
