    Disable DEP in Windows Vista = BSOD
    Disable XD in System BIOS = BSOD
    Any combination of the two = BSOD

    What is up? I suggest others try it and see if you get the same result

    DEP needs to be on for the OS to work properly.

    It is probably because something else in the BIOS changes, that XP cannot handle. I cannot prove it, but that is my hunch.

    What are you using? Vista 32 or 64 bit???

    "" DEP is ran in a software mode and in a hardware mode. If your processor supports DEP (NX for AMD, and XD for Intel), then you will have hardware and software DEP. If it doesn't, then Vista will just use software DEP. 64 bit applications will have DEP enabled all the time by default, but 32 bit applications do not and must have DEP manually enabled for them.""

    http://windowshelp.microsoft.com/Windows/en-US/Help/186de3d0-01af-4d4c-981d-674637d2f4bf1033.mspx

    "" Do not disable DEP, or exclude (OptOut) a program, unless you have adequate protection and are having problems only with a known safe program that DEP will not let run and you cannot live without it. Remember DEP stopped the program for a reason. Either it is just a improperly running program, or some sort of malware trying to get into restricted memory. ""

    See if you can turn off the hardware mode of DEP (I have no idea if this could be done / how to do it)

    But why do u want to turn off DEP? You can configure it for 'turn on only for applications except for those I select' or something like that... if its a software DEP, I would guess you would need to have it on...

    I don't need to disable it, but it would be nice to have the option =] ... apparently dell has set something that makes this near impossible, perhaps?

    Well i am not into computers, but if it says the DEP runs in software mode, doesnt it mean we need to have it enabled or at least enabled for certain programs??
