Thanx for quick answer!
As it is clear from the outpout file of the Intel Identification Utility your processor does not support Hyper-Threading technology.
But there is something wrong with your output file in my opinion. Your system is running with an FSB of 800MHz. Under this condition there is only on Northwood processor that is running with 88MHZ FSB and it supports Hyper-Threading as is clearly stated at following link:
What is the motherboard (Vendor and Bios Version) that you have installed your processor?
> But there is something wrong with your output file in my opinion.
Yea! I told you the same! I was supersured that this is Northwood. Unfortunately now i'm sure just at 87,6% that this is not_broken Northwood
Here is info:

If your Bios info are correct. (because there is a v2.0 Same motherboard), you are at bios level R1.00.
Albatron website states that this is the latest (and only-one) BIOS.
I know that is something that it is painfull but i would recomend a fresh install of WinXP Pro with SP3, just to check there isnt something wrong with your installation. If you are still see only 1 core at system properties, then i would recomend to replase your mobo. I Strongly beleive that your processor is OK and the problem is your mobo.
Sorry if i could not help more on this.
Any BIOS set-up options to enable Hyper-Threading?
> Any BIOS set-up options to enable Hyper-Threading?
Yea. And it is turned right on. And the 1st boot screen shows yellow string "Hyper-Threading is ON" - i've already described it in the very first post.
fsofos, thanx for your ideas. About windows reinstall ... mm... i've installed this copy of WinXP not very long time ago - about 1,5 years. Anyway... I have no any different installation CDs of XP yet. I'll try to dwnld couple and make boot flash from iso. Your answer has led me to believe that there is something not very good with mobo. I know that Albatron has abandoned support of this mobo and there weren't any new BIOS revs. If updates were there i would update my mobo of course. Anyway, i'll try to check this stone at different mobo first if i'll find one.
One thing which really confuses me totally out - Ubuntu sees 2 CPU's. And shows their load absolutely natural. As like as everything's fine. The load of 2 CPU's there isn't identicall but resambles each other. When no application runing the load of 2 CPU's is almost 0. bout 1-3% maybe. Then if any programm starts the load grows up at both CPU's though not absolutely identical. It might be compute 2nd graph as f(1st(t) + random_epsilon(t)) lol. Really dunno to do. Ok. If i'll find this situation out i'll post here the conclusion. If there only be supertesting utility which says all the processor features indifferently of OS or Mobo....
You might try restoring the bios defaults and / or a processor retest if teh BIOS has one.
Some BIOS test the Processor once and then sets internal values flags. (ie set up on your celeron, so HT is disabled?)
If Ubuntu sees 2 CPU's then it is probably a problem with your WinXP Installation. If you setup your system from scratch with no drivers, just to check or maybe i have a better idea, why not istalling WinXP into a virtual machine just to sees how your system behaves...
fsofos, sorry that confused you a bit. I've made some more precise view at Ubuntu's watchers. Native watch also sees 1 core. Screenlets show two, but i think they call CPU0 - the main CPU and CPU1 - the GPU. So in the end none of OS sees 2 cores. I should make some checks with your hints! Thanx! I would make it all faster if i haven't so much work.
Doc_SilverCreek, i made total drop to defaults with hyperthreading turned on. Now i should reinstall one of OS' i think... it will take time i guess couse i need to backup lot's of stuff. Find time for this. Anyway, thank you, friends, for help!
I think the truthfulness (probability?) of things that could happen to me.
damaged (defective?) CPU: 1-20%
bad or buggy Mobo or BIOS: 50-100%
bad OSes: 1-10%
somethin else: 1-10%
Ah. I remember one thing (it was several years ago) - when i have installed this CPU into this Mobo instead of Celeron 2.4 suddenly onboard soundcard became not working. I've dropped to defaults. Turned it on'n'off in BIOS etc, but it just gone. When i set back the Celeron the onboard soundcard worked fine again as before. So the onboard soundcard have some conflicts with CPU? Anyway i had to turn it off in BIOS and buy separate soundcard. So this mobo is very buggy...
