    It's quite common problem that Vista x64 will not boot or even launch setup GUI when PC has 4GB of memory, while it runs fine with 2GB.

    Vista x64 gives BSOD "STOP ERROR" "BIOS not ACPI compliant"

    Solution for Gigabyte GAMA790FXDS5:
    Loading "optimised defaults" in BIOS helps.
    The setting causing this issue is: DISABLE ON-CHIP SATA
    If you have 4GB, you can't disable SB600 SATA in BIOS !

    You can use your HDDs with jmicron "GSATA", but leave SB600 SATA enabled anyway.

    I hope that it helps someone.
    It took quite a lot of googling, contacting support to find this.
    I hope that other desperate people searching for this BSOD will find this forum and post.

    Note that this is other 4GB - related problem than infamous pre-SP1 (kb:929777) one.
