I'm having exactly the same problem. but with an ASUS P5ND2-SLI (bios
version 501, carrying a Pentium D 830, and trying to run XP x64 Edition.

I installed x64 Edition and discovered the problem, and followed up by
updating the BIOS from version 101 to 501, according to the ASUS
directions (and I have to confess that the flashing program was slick...)

Now, The BIOS POST reports "2 CPU's". I ran a repair installation of XP
x64, but the installation did not replace the HAL components to enable
the other core.

The whole point of this exercise was to get into a dual core machine.
How do I fix this?

I think that when you are doing the repair, if you hit F5 when it prompts for the F6 for additional
drivers that it will prompt you to select the HAL.

Hello Rob,
You may want to try this update. It doesn't reference XP X64 (only x64
Server versions are referenced) but it certainly sounds like the same issue.

899656 Not all processors on some multiprocessor computers are recognized
by x64-based versions of Windows Server 2003
http://support.microsoft.com/default...b;EN-US;899656

Thanks,

OK. I applied a repair install, pressing f5 to choose the multiprocessor
HAL. No change.

After applying the patch, the hardware Device manager still reports the
computer as "ACPI Uniprocessor x64-based PC", with only one entry for
the processor in the "Processors" section. That entry reads "Intel(R)
Pentium(R) D CPU 3.00 GHz.

I'm going to apply everything I can think of from Windows Update, and
then reapply this patch.

Windows Update complete, no change; the system is only using one core.

Where do I go from here?

Rob

See the ASUS web site. The D830 is listed as supported on that mobo in
single core mode only.

No... That matrix shows the D820 in single core only support. Mine is a
D830. I'm in a conversation now with ASUS where they guarantee that dual
core support is available with my BIOS version, the D830, and XP x64.

This is beginning to be more than a little frustrating.

Rob

It definitely sounds like an ASUS problem. though in fairness to them, Intel
was a bit shaky about dual core requirements -- things are not nearly so
shaky on the AMD side. There, most folks required a BIOS update, but then
they were good to go without further issues.

They assured me by phone that the latest BIOS update correctly describes
the D830 processor.

Hello Rob,
So have they tried running Windows on these motherboards with these
processors and do they see the same issue as you or does it work properly
for them?
If it works properly for them, then it's a matter of detereming what is
different between what they are testing with and what you are using.
My first thought is the same as Charlies, that the indications are that
there is a bios issue.
Thanks,
Darrell Gorter[MSFT]
