Solution

1.Load latest version of Compaq Workstation SSD for Windows NT.

2.Replace the system board.

1.Replace the controller or the system board.

2.Boot the workstation without the network drivers. Using a system boot diskette, reconfigure the network controller.

1.Be sure the cable is securely attached to the network connector and the other end of the cable is securely attached to the correct device.

2.Be sure the cable is attached to the correct connector.

3.Be sure the cable and device at the other end are operating correctly.

4.Replace the controller or the system board.

5.Run Computer Setup and modify the network controller memory value.

Diagnostics passes, but	1.	Network drivers are not

	3.	The network controller
		interrupt or memory
		overlaps the interrupt or
		memory of an expansion
		board.

1.Be sure the network drivers are loaded and the driver parameters match the configuration of the network controller.

2.Select the Network icon at the Control Panel. Reconfigure the driver if necessary, using the Network Setup found in the Control Center.

3.Run Computer Setup and modify the network controller memory value.
