How to go from single P4 to dual Xeons without reinstalling OS ?

Discussion in 'Intel' started by Luke Piasecki, Dec 11, 2003.

  1. Hi,
    I'll be upgrading to dual Xeons 3.0Ghz ( from single P4 2.4) in a few weeks
    (running XP Pro).
    I wonder if it's possible to just switch the motherboards and CPUs and if
    the OS will automatically install the MP kernel, or will I have to reinstall
    everything? I've got tons of software installed and I would have to
    reinstall everything if I were to reinstall OS... so my question is how can
    I go about switching to dual Xeons without reinstalling Windows XP Pro?

    Thank you,

    IIRC this has worked since Win2K (though I don't remember if it's
    automagical, you may have to change the computer type in Device
    Manager). However, in your case you're not just adding a CPU, but
    switching chipsets (I assume), so you may run into other problems.

    If you want to avoid BAD Registry errors, reformat your harddrive and do a
    CLEAN install of XP. You'll thank me.

  4. Just do a repair install of XP (basically reinstalling on top of itself)
    after you switch. However it's possible you won't need to do so since I'm
    sure the P4 mobo and the Xeon mobo use the same chipset drivers; it won't
    hurt to try to boot up right away. If it doesn't work you'll get a BSOD
    saying unmountable boot volume or somesuch, in which case boot of the XP CD
    and do a repair install.
