PE4600 and Red Hat Questions

[Marc Schmitt]

Hi Arjan,

Some time ago I asked on this list what Processor Family should be 
selected for the PE4600 in a custom kernel build: 
Pentium-III/Celeron(Coppermine) or Pentium-4.
So far, there was no answer.
The PE4600 has PIII Xeon CPUs which support HT. HT is a feature of P4 
CPUs (right?).

Can I select Pentium-4 as Processor Familiy w/o running into troubles, 
hoping on a tiny performance gain *for free*?

TIA

Regards,
	Marc
