    Hi Guys!!

    It had a post

    http://forum.notebookreview.com/showthread.php?p=2857318#post2857318

    Where I explained that only one processor was using the Core 2 Duo. I finally know it was because I installed under Standard PC with C-Step i486 (Which was the only option I Got it by pressing F5. Why??)
    The Question is: I wanna make a fresh XP Installation. WHich of the HAL Is the better for Core 2 duo?

    • ACPI Multiprocessor PC
    Applies to a multiple-processor ACPI computer.
    • ACPI Uniprocessor PC
    Applies to an ACPI multiple-processor board but with a single processor installed.
    • Advanced Configuration and Power Interface (ACPI) PC
    Applies to a single processor motherboard with single processor.
    • Compaq SystemPro Multiprocessor or 100% Compatible
    Applies to a Compaq SystemPro computer.
    • MPS Uniprocessor PC
    Applies to non-ACPI computers dual processor motherboard with a single processor installed.
    • MPS Multiprocessor PC
    Applies to non-ACPI computers with a dual processor running.
    • Standard PC
    Applies to any Standard PC, non-ACPI, or non-MPS. The CPU may be a 386, a 486, a Pentium, a Pentium II, or a Pentium III.
    • Standard PC with C-Step i486
    • Other

    for "windows", is Core 2 duo 2 actuals processors ?

    Thank you very much!

    Use the ACPI Multiprocessor PC HAL if you want windows to appropriately recognize the CPU's. This is because the ACPI HAL's (i.e. uni and multi) are designed to manage IRQ's in your system while MPS uses individual IRQ's. Also ACPI takes over the PnPBIOS and Multiprocessor Specifications (i.e. MPS). So if you want Windows to utilize your c2d (and be able to see TWO cpu graphs in your task manager->performance tab instead of just ONE) use ACPO Multiprocessor PC.

    Also you say you only saw 'Standard PC' option after pressing F5. Did you try to scroll up with the up arrow on your keyboard? I only ask because I know it can be decieving but it only shows two options at a time at this prompt so..
