step 5 in Reinstalling Windows NT Networking.
Advanced Installation Options
=============================
Running Windows NT on a Non-Intel Processor
-------------------------------------------
If your system cannot run the 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 manually by
using the MEDIA keyword. To set the MEDIA keyword, add the key MEDIA to
the registry in the subkey:
\\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\El99x?\Parameters
NOTE: Multiple subkeys that look like El99x 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 (for
example El99x1). The incorrect one simply reads El99x.
The value for the MEDIA keyword should be one from the list below. The
default is NotPresent.
MEDIA 10HALF <-- 10 MBPS with half duplex
MEDIA 10FULL <-- 10 MBPS with full duplex
MEDIA 100HALF <-- 100 MBPS with half duplex
MEDIA 100FULL <-- 100 MBPS with full duplex
MEDIA AUTO <-- Driver performs auto configuration
MEDIA NotPresent <-- Use settings in NIC
