    Sirs,

    There is a bug in the CELERON D Prescott C-0 that prevents this
    processor to reboot the machine. This processor hangs when you try to
    reboot the machine. The people from ECS had already released in
    2005/01/11 a BIOS update that covers this problem to the motherboard
    648FX-A2(PCB:1.0).
    Here is the update description of the BIOS:

    "1. Add support Prescott E0, C0 stepping CPU
    2. Update Prescott CPU Micro code
    3. Patch some Prescott 2.4G CPU (FSB533/1M) cannot restart under WinXP"

    And Microsoft have released a workaround for this problem too:

    "(KB885626)
    This non-security critical update helps resolve an issue where a
    limited number of systems running a BIOS without production support for
    Intel Pentium 4 and Intel Celeron D processors based on Prescott C-0
    stepping can potentially hang on Windows XP Service Pack 2
    installation."

    Maybe someone from Intel can point to us where is the fix or errata of this
    problem? I wan´t to create a patch to workaround this issue.
    I´m having some problems with this processor using motherboards
    from MSI - 661FM-L.

    Thanks.

    Camilo
