Win Vista with Multiproccessor CPU ids as a "X86 ACPI PC".

Guest

MY system has a AMD 64 X2 dual core processor. In the Device Manager,
Computer, it shows as "ACPI X86 Based PC" instead of "Multiprocessor ACPI
Based PC" or similair. When I try and change the driver, the Multiprocessor
ACPI choice is not shown.

How do I get the correct HAL to be used?

TIA,

John

Hi,

That'd be normal if you have the 32-bit version of Vista installed. Your
processor leg should show both cores and label them accordingly, but since
the OS is 32-bit, it's running as an x86 system.

Thanks for that information! I imagine this is an "experience" sourced bit of
knowledge on your part. Is there a reference base available besides extensive
OS training and experience for obscure system info like this documented
online someware? :>)

That entry in Device Manager does NOT mean that the operating system is 32-bit.
It means that the processor is based on the Intel XXX86 CISC (complex
instruction set computing) architecture as opposed to other processor
architectures such as RISC (reduced instruction set computing) like the Power PC
and the SPARC processors. (NT used to support other microprocessor
architectures.)

To check the bits of the OS you need to go to Control Panel > System.

Hi,

Check again, it's not CISC vs RISC. It's not under "processor" that the OP
was referring to, but under "computer" in device manager. A 32 bit OS will
report it as being x86 ACPI compliant, and 64 bit will list as being x64
ACPI.
