I have a comment about Making 
Sure the Correct HAL is Installed:

ACPI HAL Multiprocessor Fix.  
Perform the following steps on a workstation that has multiprocessor core available 
and currently is not showing both processors in the task manager. (Not showing both 
processors means in the task manager does mean that the 2nd processor is not being 
used.)


>START

 >Right Click MY COMPUTER

  >MANAGE>DEVICE MANAGER

    >Expand COMPUTER

     >Right Click ACPI

      >PROPERTIES

       >DRIVER

        > Choose ROLL BACK DRIVER

When you choose ROLL BACK DRIVER the machine will want to reboot. Since every XP 
Professional machine has all available HAL’s it will automatically identify the correct 
HAL that should be on the machine.  Allow the machine to reboot and you should then 
be in the ACPI Multiprocessor Mode.  To verify go to task manager and look to see 
if both processors’ details are shown.  Verification can be performed also by looking 
in the DEVICE MANAGER under the COMPUTER option and the setting should now read ACPI 
Multiprocessor.  There may be one error that gets presented that requests the location 
of a driver.  XP should default to that location.  Choose RETRY and it will complete 
the install.
