Hi,

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.

Symptom:
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.

Cheers,
