    Ive been posting this last time but they said to flash my bios but i don't think it is not the bios compatibility because long time ago i we have already installed XP and it doesnt hang. but we just notice the hang only this year

    my new hardwares i bought this year:
    an AGP ASUS Geforce 2 MX 400 Video Card
    512 MB RAM
    LiteON 52X24x52 CD-Writer

    Memory is not the problem because we have change slots remove RAMs making it single then still XP hangs. It is not the CDWriter because the hanging happened before we bought the CDWriter. I don't know with the video card but i think the error is on the BIOS Setup configuration. Can you help me find it out.

    The error is see Event Viewer

    AMLI: ACPI BIOS is attempting to read from an illegal IO port address (0xcfc), which lies in the 0xcf8 - 0xcff protected address range. This could lead to system instability. Please contact your system vendor for technical assistance.

    What is 0xcfc, 0xcf8, and 0xcff and what are protected address range?

    Did you reset the BIOS to it's defaults with the MB jumper?

    The AMLI (ACPI Machine Language Interface) is dependent on the motherboard and BIOS that supports it. If you have an older version of the ACPI implementation, and a BIOS update doesn't help, you need to reinstall as a Standard Computer (F5 during setup) rather then an ACPI-compatible computer. This will remove the error.

    As Ronnie151 said, it is usually nothing to worry about unless it leads to specific problems like yours.

    The state of enablement of ACPI in the BIOS may not effect XP's BIOS overrides for it's own purposes.

    The question is which HAL (Hardware Abstraction Layer) was used during installation. An ACPI HAL wil try to use ACPI power management on the machine, but the HAL for a standard PC will not. The HAL used appears under Computer in Device Manager.

    If ACPI doesn't function prefectly, get rid of it by reinstalling using a different HAL.
