XP Pro not recognizing second processor ???

Motherboard A7M266-D
Processors AMD Athlon 2800+ (x2)
Both show up fine in the BIOS and can be monitored
via the ASUS utility for temperature and vcore
Device manager:
shows 2 processors under processors
Shows ACPI Multiprocessor PC under computer
now the bad news...
environment variables show
NUMBER_OF_PROCESSORS = 1
and the registry has a couple of entries that are also
NUMBER_OF_PROCESSORS = 1
task manager under performance also will
display only one CPU graph
I am assuming from this that the PC is only utilizing one
CPU and I'm wondering how to fix this

I am assuming you installed the second CPU after you
installed the OS. Do a reinstall of XP Pro.

No, it has always been a two processor machine,
but the processors have been upgraded
I believe that the computer being identified as
ACPI Multiprocessor PC
indicates that it has the correct (multiprocessor)
kernel installed.
I was hoping to avoid a reinstall

Which CPU's did you upgrade to; the Athlon MP or XP? If memory serves the
Athlon XP does not work in multi CPU configurations.

Well its just a long shot, but you could add the /numproc=2 to the boot.ini
file. This should force the system to use both processors. Since its already
configured as a "ACPI Multiprocessor PC" you probably have the correct HAL
and ntoskrnl.

Still no luck....
Poked arounnd the registry a bit more though....
KEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProce
ssor\
and
HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\FloatingPoi
ntProcessor\
have only one processor (0) the data in
[HKEY_LOCAL_MACHINE\HARDWARE\ACPI\DSDT\ASUS\A7M266-
D\00001000]
makes reference to cpu0 and cpu1 though
