Changing the Windows NT Registry

If the PC cannot run the Configuration and Diagnostic Program, you may need to set the NIC speed and duplex level in the Windows NT registry.

CAUTION: Mistakes in the registry can cause system crashes. Be sure to save a copy of the original registry settings before you make changes, so that you can restore the registry if necessary. If you are not sure about the registry settings, consult with a knowledgeable network administrator before proceeding.

You can set the NIC speed and duplex level in the registry by setting the MEDIA keyword in this subkey:

\\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services \E190x?\MEDIA keyword

where keyword is one of the following:

100HALF	100	Mbps with half-duplex operation
100FULL	100	Mbps with full-duplex operation
AUTO	Driver performs auto configuration
NotPresent	Use settings on EEPROM

The default MEDIA keyword setting is NotPresent.
