AHCI in BIOS

[SeriousTom]

I have a GA-990FXA-UD3 (rev 1.1) and had been using the F9 BIOS, and had the OnChip SATA Type as AHCI and it had been running fine under Windows 8 Pro 64 bit but I read hear that Corsair has a new ToolBox for their SSD's so I thought I would update my BIOS to the new BETA F10a that says Update AHCI ROM version and then install the Corsair Toolbox.
I didn't get far,
I loaded Optimized Defaults and then flashed F9 to F10a and then loaded Optimized Defaults and Booted into Windows.
So next I changed my OnChip SATA Type from IDE to AHCI and Windows starts to load but says it ran into a problem and reboots loop.
So I went back to F9 but any time I switch from IDE to AHCI Windows won't boot.
What can I do ?
I have a nice fast Corsair SSD running in IDE.
I'm hoping their is a solution.

Re: AHCI in BIOS

Well, that wasted a morning.
Moral of the story.. if you Load Optimizied Defaults make sure that AHCI is enabled before hand or maybe the new BIOS should check to see if AHCI is being used (Gigabyte) because this stinks.
I did all the registry tricks, changing 3 to 0 and none of that stuff worked.
I even tried putting the installation DVD in and running tools ...nothing !
The easiest thing worked ... I went to msconfig and started in Safe Mode, and when it restarted went into the BIOS and selected AHCI again, it Booted into Safe Mode.
That's it !
Next time it restarted in Normal mode with AHCI.
Just in case somebody needs to know.
