@doodio- To downgrade back to R1031H4 you must First upgrade to one of the UNLOCKED BIOS's posted by Camilo. Once you are upgraded you can now revert back to the Original BIOS. ; If it still wont let you downgrade to original BIOS you can always "downgrade" to
Camilo's Unlocked R1031H4 BIOS with advanced menu (same as Original, just with advanced menu.
@frozst -
For AHCI Go to the advanced menu in the unlocked bios from Camilo, and go under SATA/RAID/Hard Drive/Controllers..etc.. (I am not sure which one, but you get the idea. Vaio's default setting is RAID. Now change RAID to AHCI and save and restart; Windows will detect new hardware and Install drivers for (can be seen under controllers in device manager), Intel® Mobile Express Chipset SATA AHCI Controller! Before it was listed something like Intel bla bla RAID Controller.
Make sure your intel chipset drivers are up to date, my Vaio is 2 weeks old and I was able to update to new chipset drivers, Rapid storage, Intel Management Engine Interface, etc.. I use a free program called DriverMax to get driver updates.
Sony Driver Update
Intel Rapid Storage Technology (SATA AHCI) 10.8.0.1003
And after all that if AHCI still does not work (THIS WILL WORK, Probably Should do this step First lol , Before you change to ACHI mode in BIOS
(if you already have, change it back to RAID), THAN you can enable AHCI via registry before you change the SATA mode of the boot drive:
Exit all Windows-based programs.
Click Start, type regedit in the Start Search box, and then press ENTER.
If you receive the User Account Control dialog box, click Continue.
Locate and then click one of the following registry subkeys:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\IastorV
In the right pane, right-click Start in the Name column, and then clickModify.
In the Value data box, type 0, and then click OK.
On the File menu, click Exit to close Registry Editor.
NOW go back to BIOS and switch to RAID TO AHCI, now restart the computer and it should install the new AHCI controller.
Intel Rapid Storage now says "Your system is configured to enable advanced SATA features for optimal power management and increased storage performance." Before the standard BIOS was set to RAID and Intel Rapid Storage did
NOT say drive was set for increased performance. Now you have Faster Drive Performance and Intel Rapid storage software says your drive is set for increased storage performance!

Sata3 is only available on R1031H4.
Well that's just a shame. This is really a kick in the teeth to all sony SA/B/C/E owners. Clearly just a ploy for Sony to make you purchase their crappy overpriced SSD version. I think we should start an online petition for all S series owners to make them re-enable it. It's complete nonsense to purposely disable working hardware and punish owners who have already spend 1K+ on their laptop.
On that note, is their any risk in upgrading and then trying to downgrade to the R1031H4 bios? Right now when I try to install it it still says my version is current and won't let me do it with the unlocked bios.
