P4 Hyper threaded CPU is only showing 1 CPU under task manager

I have recently re installed ( clean install ) XP MCE and cannot see 2 cpu's under task manager.  There is no selection under view/cpu history , just one graph per CPU.

The CPU is P4 3 Ghz prescot that has been running quiet fine for some time. The bios starts and shows Hyper Threading enabled and I have downloaded utility from intel witch also shows that it is a Hyperthreaded CPU.  

Is there a registery setting of some kind to check or some other are to look at before i start swapping CPU's?

Open Device Manager (right-click on My Computer; select Properties; click the Hardware tab; then click on Device Manager);  then expand the "Computer" (click the "+" sign); and see what hardware abstraction layer (HAL) is installed -- it should say "ACPI Multiprocessor PC"
Go into your BIOS at startup.  Some BIOS need you to enable the CPU also that gives you a chance to see if the CPU is actually recognized in the lowest level.

I have expanded computer and it sais standard PC - does that mean the ACPI is not running?

Does have to be set under bios?
I no the bios is allready set for Hyper threading enable
Hyperthreading does not mean 2 CPUs.  It means a single chip is acting like 2.  What brand of computer is it?  The bios should tell you one or two processors is what is sees.

No that you mention that it makes perfect sense. I used a new utility called nLite to create unattended install. it asks for the type of HAL, witch I left @ default i think, witch is where i beleieve the problem arose.

So when the install asks "Press F6 if you have to install a third-party SCSI or RAID driver" i should press F5?
Yes, that will work.   OR just do a complete new install and let XP automatically set it correctly.
