    Just after Starting Windows comes up, the install bluescreens with a 0xa5 error saying that my BIOS is not ACPI compliant.

    This is a Giga-byte AMD740 based motherboard running a Phenom 9550 with 4GB of RAM.  I tried pulling most of the hardware and turning most things off in the BIOS but no luck.  I am at the latest BIOS Giga-byte offers. 

    Is this just a bug with beta 1?

    Actually, stangely enough, I can recreate it time and time again if I enable/disable the SATA controller.  Don't know why turning it off would make the BIOS to appear as non-ACPI complaint.

    Did you try changing the power states in the bios?

    Sorry, don't know what you mean by power states in the BIOS.

    You know... the acpi suspend type ... i.e. S1, S3 or S1&S3.

    Also make sure ACPI APIC support is enabled.

    The bios has got to have that stuff in it.
