Adding Support for Multiple Processors in Windows XP Pro

[Sean]

I upgraded my motherboard and added dual processors, but
I don't see them recognized in the Task Manager. How do I
make my existing installation of Windows XP understand
that it now has dual processors?

Hello

Did you do the following below, also in your system Bios check and
verify
those settings. During the upgrade process did you do the following.
Also
according to your note you do have Win XP Pro and not home correct
XP Home does not support Dual Processor but XP Pro does, this was
just a note to ask.

Do a repair install

Set the BIOS to boot CD before Hard disk, then boot the XP CD, start
Setup (do not take 'Repair' at this stage), then after the license
agreement take 'Repair Installation'. This will retain your existing
software installations and most settings. But Updates will have to be
run again, especially SP1; and if you have drivers that only arrived
with that, like USB 2 ones, you will need to update drivers for the
devices concerned. You may find that things like virtual memory
settings and some aspects of appearance have reverted to defaults

At the first reboot, You will get a black screen with a white bar -
'Hit F6 to install special. . . '. Hit F5 instead; you will get a
chance to select a 'HAL' - choose the standard multiprocessor one
