>Description:
When installing NetBSD 5 on a system with an Intel Xeon QuadCore processor and 
Intel server motherboard with 8 GBs of RAM, only one processor was detected.

The "fix" indicated below resolves the problem, and should be included in the 
INSTALL documentation in order to help others.

>How-To-Repeat:

>Fix:
In the BIOS settings, under "Processor -> Advanced" enable the "Multi-Thread 
Support In MPS table" option to use all cores on "Intel Xeon QuadCore 3000 
Sequence" processors with Intel S3200SHV and S3210SHLC motherboards.
