OSR6 Processor confusion - P4 Xeon Extreme Hyper non-sense.

http://www.sco.com/products/openserver6/requirements.html

On the System Requirements page for OSR6, many processors are listed
from Celeron thru Xeon thru AMD processors. In the recommended column,
is listed "Pentium P4".

(1) which P4 are they recommending? Intel lists

Intel® Pentium® 4 Processor
Intel® Pentium® 4 Processor supporting Hyper-threading Technology
Intel® Pentium® 4 Processor Extreme Edition supporting
Hyper-Threading Technology



(2) Intel also makes the Intel® Xeon® Processor, Intel® Xeon®
Processor MP, and Intel® Itanium® 2 Processor. Are these a waste of
money with OSR6? Aren't the Xeon superiour to the P4??
