How to enable NX in bios for Win8

Hi, have a dell dimension 8400 and trying to install win8 but getting error code relating to NX enable in bios. Updated bios to A05(which specifically mentions enable of NX) but cannot find anything in bios settings to do this. Any ideas? Cheers

Hi,

 NX stands for No eXecute and it is a technology used in processors to prevent execution of certain types of code. This was originally invented by AMD.

 XD is the acronym for eXecute Disable, which is an Intel specific implementation of NX. It refers to the same feature but Intel chose to call it by a different name.

 In Dimension 8400 the processor is Intel, which would use XD instead of NX.

 Also, attaching a BIOS image for your reference

 

Please reply if you have any further questions.

Thanks and regards,

Hi, thanks for reply. This option 'execute disable' in Bios settings is not available to me. Have updated bios further to A09, but again no option here, just the 3 tabs referring to passwords.

Hi,

I've the same problem with my optiplex 755, I enable it (BIOS), but the windows 8 installer didn't find the feature, like VirtualBox...

Very strange problem.

I am using a Dell Dimension 5000 with Intel Pentium 4 / Intel i915G Express Chipset.

I have the same issue. I guess this cpu is simply not able to run this "Execute Disable Bit", as I read this Intel datasheet :

http://ark.intel.com/products/27463/Intel-Pentium-4-Processor-530530J-supporting-HT-Technology-1M-Ca...

I updated the bios to A07 but the option is not available because of the hardware.

Thanks for any help in case there is a solution.

Hi Madhur! I have the exact same problem. I have a Dell Dimension 8400 P4. Coreinfo results indicate my processor is NX capable, and I've applied A9 bios upgrade with no visible options for turning that feature on or off. I'd like to upgrade to Windows 8, stops short due to NX not being turned on. Any assistance would be greatly appreciated. Please email me, [ADMIN NOTE:  Email address removed per privacy policy], if possible, I'll supply you my Dell Tag. Thanks in advance!

So were you able to resolve the problem?  If so how?  I have an xps 9000 that I would like to run 8 on.

 

Thanks...
