Disable Hyperthreading on an Acer Laptop

[benners]

I have an Acer Aspire 1710 series notebook and would like to disable Hyperthreading, I can find nothing in the limited bios options as you would a "decent" computer, so, does anyone know how I may accomplish this?

Many laptop bios's are very limited.

However i have noticed on new laptops alot of the advanced options are hidden.

Check the manual see what it states about the bios.

I have checked the manual but found nothing about advanced features or menus.I tried key combinations but nothing.... I was hopng Intel might have a prog that could force HT off but I could only find a test util

Can't it be possible from within XP itself, to tell it use only one processor (as effectively HT is enabled with multi-proc). Msconfig has no switch for this. But might be that bootcfg has an option to pass to kernel?

(dunno 'bout this, just an enquiry)

Just out of curiosity, can I ask why you would want to do this? You ended up shelling out more money for the HT feature... so why disable it?

@prathapml

There is a switch for the boot.ini its /NUMPROC, I have tried but no joy, I think it only works for actual multi processor systems, and once they MP kernel files are loaded they stay on the system, so I would prefer to disable before loading XP, at least thats how I understand it.

@Zxian

My main reason is Xplode, certain plugins fail to load with HT turned on, I have run my unattended disc on the desktop PC with HT on and the directory plugin failed to load, turn it off and the process runs smoothly, if I had the option of buying the same laptop without HT I would have, bit of a white elephant in my opinion, forced upon us by the CPU nazis /rant
