GA-Z77X-up5 TH USB3

[pehera]

Hi
my request is not to unlock but to lock a bios feature on my GA-Z77X-UP5-TH
Bios (Uefi) version F11

http://www.gigabyte.us/products/product-...=4279#bios

In the bios there's an option in Peripherals called "xHCI Mode = Smart Auto"

From manual:
"Smart Auto
This mode is available only when the BIOS supports the xHCI controller in the pre-boot environment. This mode is similar to Auto, but it adds the capability to route the ports to xHCI or EHCI according to setting used in previous boots (for non-G3 boot) in the pre-boot environment. This allows the use of USB 3.0 devices prior to OS boot. xHCI controller enabling and rerouting should follow the steps in Auto, when previous boot routs ports to EHCI. Note: This is the recommended mode when BIOS has xHCI pre- boot support."

The on-board USB 3.0 port function like a 2.0 port before OS USB 3.0 driver load.
If you reboot the OS, during this reboot BIOS phase, BIOS is "Smart" enough to avoid downgrade the USB 3.0 port back to 2.0 functionality before OS USB 3.0 driver load. So Smart Auto is faster than Auto on 2nd boot onward.

Bios is dependent on Windows/USB3 driver to make that smart feature step in.

I'm dual booting Windows and OS X 10.8.3 on my comp and it's not a big problem for me but for many other that dosn't have windows on their hackintosh

Can that "xHCI Mode = Smart Auto" be locked so that the USB3 ports won't be downgraded to USB2 ?

If so i would also like to have Slic 2.1 (Gigabyte)
