In a <A HREF="http://www.theinquirer.net/?article=18414" target="_new">news</A> article intel recommends "All operating systems apart from Windows XP, according to Intel, should have hyperthreading disabled. Those include Windows 2K, Win NT 4.0, Win ME, Win 98 and Windows SE."

No reason offered. I'm going to be cynical conspiracy theorist here and say the reason is: Microsoft has delayed 64 bit windows for Intel, so now Intel is trying to create a perceived need for an OS upgrade?

Pure fun speculation here...
edit - I should add the implication on their site is that those OSs don't support hyperthreading. Is that really true? I thought 2000 did.

The fact that HT is best supported in XP than all other of MS OSes is already very, very old news.

The inquirer published it as something new, but it's not.

Why are you all so surprised?

Well, it is (was) known that XP was based on 2000 core. Hence 2000 should have equal HT support as XP. But as they reported, its not the case.

And it might be old news, but its said by intel now to disable it rather than saying anything but xp has bad support.

Absolutely, Xeon.

I can't understand why everybody is making such a fuss about that ridiculously misinformed theinq article.

This is very, very old news. Only XP actually knows how to deal with HT. This is microsoft's fault, not Intel's.

Oh, and if XP is just a revamped 2000, then I'd argue that the 2000 is just a revamped Windows NT 5.0, which is also a revamped NT 4.0. You know what this means????? NOTHING! (Why are we all using XP instead of WinNT then?)

you're a moron. i've known this for over a year. xp or linux is the only o/s optimized to work right with h/t. it doesn't work at all in win9x and windows 2k thinks its actually 2 cpu's so it can take a performance hit.

Geeze guys... I wouldn't call it stupid on my part, so much as ignorance. I'm not a 'doze guy so I didn't know. So does Windows server 2003 support it?

u are a moron*2, wtf do u think HT does ? See ur fuc***** system info in XP...and if u see just 1 cpu, ur HT is off. XP/2000 both have to show 2 CPUs. And so does LINUX. why the hell do u think in GRUB u gotta choose SMP option. That means symmetric multiprocessor. SMP is only possible when there are more than 1 CPU - physical or logical.

Linux kernels higher than 2.4.17 support it, although I've read briefly suggestions that it is more effective in the 2.6 series. I don't know what the deal is with Windows, I'll let one of the real ultra geeks(TM) cover that.

Hey I'm just being a smartass, since "ultra-geeks" supposedly would know about windows issues. :) I honestly have nothing against that virus known as windows.

It's not good bye all games under Linux though... D3 will be out soon and if you own the windows version, you can run it under linux now. America's army is out for linux, Unreal tourney 2004 is out for Linux. Personally, I only ever fireup neverball and foobilliards myself. Thought I should say something. The game situation is slowly changing under Linux.

Never knew about this and just realized how stupid I was. I recommended a P4 2.8C as our office server expecting that HT would somehow contribute to the efficiency. It's running on Win2000 Server. Only to know later that I should disable HT on that machine?

Should have gone for an AMD64 3000+ which we use in our workstations.

Uh, d00d, we already knew this years ago when the 3.06 was still pre-realease. 9x doesn't even support dual processors, so of course it can't support 2 logical processors.

I don't think MS cares, they have XP and 2003 to push right now.
