ADVANCED INTALLATION OPTIONS ---------------------------- Running Windows NT on a Non-Intel Processor ----------------------------------------- If your system cannot run the DOS-based Configuration and Diagnostic program, you may need to set the speed and duplex level of the NIC in the Windows NT registry. The speed and duplex value of the NIC can be set manualy by using the MEDIA keyword. To set the MEDIA keyword, add the key MEDIA to the registry in the subkey: \\HKEY_lOCAL_NACHINE\SYSTEM\CurrentControlSet\Services\El90x?\Parameters NOTE: Multiple subkeys that look like El90x appear right next to each other. The correct one has a digit in place of the ? in the above expression to represent which NIC it is. The incorrect one simply reads El90x. The value for the MEDIA keyword should be one from the list below. The default is NotPresent. MEDIA 10HALF <-- 10 Mbs with half duplex MEDIA 10FULL <-- 10 Mbs with full duplex MEDIA 100HALF <-- 100 Mbs with half duplex MEDIA 100FULL <-- 100 Mbs with full duplex MEDIA AUTO <-- Driver performs auto configuration MEDIA NotPresent <-- Use settings on EPROM (%VER WINNT.TXT - Installing the NDIS 3.0 Driver for Windows NT V1.0h)
