    VISTA installation load failure - BIOS is not ACPI compatible

    I am trying to install Windows Vista Beta 2 on one of my desktops running with Via motherboard. Every time I start the installation, just after installation environment gets loaded, I get an error message saying:

    “Windows failed to load because the firmware (BIOS) is not ACPI compatible
    Status: 0xc0000225”


    I don’t know why the error is saying about ACPI because I checked my MOBO’s specification and it has the ACPI support. Any idea what could be the problem and how can I get the installation completed? Many thanks.

    Hello Klums, thought your Mobo supports ACPI, but is it turned on? You need to enable the ACPI from BIOS. Do it and try again.

    Wow, you are great jean. That really helped. Actually the ACPI was turned off in BIOS. As you said, I enabled it from BIOS and installation went fine.

    Thank you.
