Dual Processors in XP

[Myles A. Castagna]

I can find no information anywhere as to enabling
multiple processors in Windows XP professional. I have an
Intel SE7500CWD moterboard that utilizes 2 XEON 2.2GHz
processors. I have tried every resource I can think of to
no avail.

I am akso a bit confused between Windos XP 32 and 64 bit
versions. Should I be using the 64 bi version with the
above configuration.

I would be most grateful to anyone with any ideas or
links that will help me solve this problem.

Thanks

Myles

When Windows XP was installed on your computer, a dual CPU HAL(Hardware
Allocation Layer) should have been installed. In the Device Manager expand
Computer by clicking the "+" sign. You should see something the effect of
Dual Processor PC. Expand Processors, You should see two. Close the Device
Manager and open the Task Manager. In the Performance tab choose View>>CPU
history>>Show one graph per CPU. You should now see two graphs or four if HT
is enabled. You should be using the 32-bit version of Windows XP Pro since
the P4 Xeon is a 32 bit processor.

"How to Force a Hardware Abstraction Layer During an Upgrade or New
Installation of Windows XP"

(Use this with a repair installation of XP,

install ought to preserve most installed programs and settings, although
you'll lose all of the Windows Update patches.)

I think that you probably want ACPI Multiprocessor.

Current Xeons are 32 bit. As far as I know, the only currently supported 64
bit CPUs are Intel Itaniums.

HTH.
