Chapter 2 BIOS Setup

BIOS (Basic Input and Output System) records hardware parameters of the system in the CMOS on the
motherboard. Its major functions include conducting the Power-On Self-Test (POST) during system startup,
saving system parameters and loading operating system, etc. BIOS includes a BIOS Setup program that al-

lows the user to modify basic system conguration settings or to activate certain system features.

When the power is turned off, the battery on the motherboard supplies the necessary power to the CMOS to

keep the conguration values in the CMOS.

To access the BIOS Setup program, press the <Delete> key during the POST when the power is turned on.
To upgrade the BIOS, use either the GIGABYTE Q-Flash or @BIOS utility.

• Q-Flash allows the user to quickly and easily upgrade or back up BIOS without entering the operating
system.

• @BIOS is a Windows-based utility that searches and downloads the latest version of BIOS from the
Internet and updates the BIOS.

• Because BIOS ashing is potentially risky, if you do not encounter problems using the current version of BIOS,

it is recommended that you not ash the BIOS. To ash the BIOS, do it with caution. Inadequate BIOS ashing

may result in system malfunction.

• It is recommended that you not alter the default settings (unless you need to) to prevent system instability
or other unexpected results. Inadequately altering the settings may result in system's failure to boot. If this
occurs, try to clear the CMOS values and reset the board to default values. (Refer to the "Load Optimized De­faults" section in this chapter or introductions of the battery/clear CMOS jumper in Chapter 1 for how to clear
the CMOS values.)

2-1 Startup Screen

The following startup Logo screen will appear when the computer boots.
(Sample BIOS Version: E11c)

Function Keys

On the main menu of the BIOS Setup program, press arrow keys to move among the items and press <En­ter> to accept or enter a sub-menu. Or you can use your mouse to select the item you want.

• When the system is not stable as usual, select the Load Optimized Defaults item to set your system to its
defaults.

• The BIOS Setup menus described in this chapter are for reference only and may differ by BIOS version.

2-2 M.I.T.

This section provides information on the BIOS version, CPU base clock, CPU frequency, memory frequency,
total memory size, CPU temperature, Vcore, and memory voltage.

Whether the system will work stably with the overclock/overvoltage settings you made is dependent on your

overall system congurations. Incorrectly doing overclock/overvoltage may result in damage to CPU, chipset, or

memory and reduce the useful life of these components. This page is for advanced users only and we recom­mend you not to alter the default settings to prevent system instability or other unexpected results. (Inadequately
altering the settings may result in system's failure to boot. If this occurs, clear the CMOS values and reset the
board to default values.)

- 27 -

&XHCI Mode

Allows you to determine the operating mode for the xHCI controller in OS.

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. (Default)

Auto BIOS routes the sharable ports to EHCI controller. Then it uses ACPI protocols to

provide an option to enable the xHCI controller and reroute the sharable ports. Note:
This is the recommended mode when BIOS does NOT have xHCI pre-boot support.

Enabled All shared ports are eventually routed to the xHCI controller during the BIOS boot

process. If BIOS does not have pre-boot support for the xHCI controller, it should
initially route the sharable ports to the EHCI controller and then prior to OS boot it
should route the ports to xHCI controller. Note: OS has to provide support for the
xHCI controller in this mode. If the OS does not provide support, all sharable ports
won't work.

Disabled The USB 3.0 ports are routed to the EHCI controller and the xHCI controller is turned

off. All USB 3.0 devices function as High Speed devices regardless of xHCI software
support/availability.

Manual Allows you to determine whether to rout the USB 3.0 ports to the xHCI or EHCI

controller before booting to OS, and also provides you with options to manually rout
