Vista - BSOD if dual core support is enabled in BIOS

I recently upgraded my CPU from an A64 3000 to an A64 4200 X2. The system now
BSOD's on bootup if I have both cores of the new CPU enabled in the
motherboards BIOS. Vista will boot in safe mode with both cores enabled and
displays both cores in the task manager. If I change the Computer mode to
"Advanced Configuration and Power Interface PC (ACPI)" from "ACPI x86 based
PC" then windows boots fine with just 1 core detected by windows.

It seems that the BSOD is caused by having 2 cores enabled. The rest of my
system has remained unchanged apart from the CPU upgrade. I've tried a fresh
install of Vista and also reverting to XP (the CPU works fine in XP).

My system spec's are as follows:

A64 4200 X2 socket 939 CPU, Asrock 939S56-M motherboard, 2GB Geil Ultra
DDR400 (4x256MB), ATI x850xt pe Graphics Card, 2x80GB Seagate SATA 2 Hard
Drives, Samsung DVD-RW, Floppy Drive.

its your drivers fault!!!!

lol now if you dont install drivers for CPU its another thing.. but its sure
is not vistas fault.. vista is sacred.. given to us from heaven!

Kneel in the shrine of the mighty V!

you need to have ACPI - MULTIPROCESSOR as your computer

I made the same exact upgrade a few weeks ago while using Vista x64. No
problems whatsoever. You don't need to worry about the ACPI thing, it
doesn't matter in Vista.

I'm guessing it's a BIOS issue.

Thank you for the 1 useful answer Mike.

I've checked the boot logs and when dual core is enabled in the BIOS I get
"Did not load driver @hal.inf,%acpiapic.devicedesc%;ACPI x86-based PC" as the
first unloaded driver in the log. It then also fails to load the driver for
my graphics card and sound card although these are probably failing due to
the first driver not being loaded. This occurs just after "Loaded driver
\SystemRoot\system32\drivers\crcdisk.sys" in the boot order.

As dual core support causes no problems at all under XP I am inclined to say
this isn't a BIOS issue and more an issue with Vista's ACPI/HAL drivers. That
being said maybe the BIOS isn't compliant "enough" for Vista, where XP turns
a blind eye.

What confuses me is if I leave dual core enabled in the BIOS but boot in
safe mode Vista doesn't crash and in taskmanager I have 2 fully working cores.

I can post full event logs and boot logs if it will help.

Cheers!

That indicates the Hardware Abstraction Layer (HAL) is not loading for
the dual core processor. Is Vista the only thing on the drive, or are
you dual-booting with XP?

If you're not dual-booting and your motherboard is over 1 year old,
then you may need to upgrade the BIOS to a more recent version that
has better processor support.

Or there may be another setting in the BIOS that you've missed. My
ASUS board doesn't give me the option to enable or disable the second
core, it's detected automatically and enabled. If your BIOS is recent,
perhaps you can go in and record the settings, then load factory
default settings. That should allow the BIOS to reset properly to dual
core settings.

All reports are that Vista is quite happy with dual core processors
(I'm running one here as well).

Happy Holidays!

I've already updated to the latest BIOS. It definately lists support for my
CPU with the current BIOS. I've tried resetting the BIOS to default settings
but this doesn't help. The CPU works fine in XP (not dual booting, tried it
before I installed Vista). I've run out of ideas now.

When you bring up the Device Manager and expand the entry for "Computer"
what does it say? That will indicate the hal.dll that is installed. Bill
may be on to something.

Did you install Vista on the new processor or old?
Suggest you request a driver for the processor from AMD.
Also try resetting pagefile settings
