Gigabyte Gaming 5 Manual

							BIOS (Basic Input and Output System) records hardware parameters of th\
e 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 allows the	user	to	modify	basic	system	configuration	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	configuration	values	in	the	CMOS.To access the BIOS Setup program, press the  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 wi\
thout 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.
Chapter 2 BIOS Setup
 •Because	BIOS	flashing	 is	potentially	 risky,	if	you	 do	not	 encounter	 problems	using	the	current	 version	of	 BIOS,	it	is	 recommended	 that	you	not	flash	 the	BIOS.	 To	flash	 the	BIOS,	 do	it	with	 caution.	 Inadequate	 BIOS	flashing	may result in system malfunction. •It is recommended that you not alter the default settings (unless you n\
eed 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 ScreenThe following startup Logo screen will appear when the computer boots.(Sample BIOS Version: D3)
Function Keys
 •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 an\
d may differ by BIOS version.
There are two different BIOS modes as follows and you can use the  key to switch betw\
een the two modes.The Classic Setup mode provides detailed BIOS settings. You can press the arrow keys on your keyboard to move among the items and press  to accept or enter a sub-menu. Or you \
can use your mouse to select the item you want. Easy Mode allows users to quickly view their current syst\
em information or to make adjustments for	optimum	performance.	In	Easy	Mode,	you	can	use	your	mouse	to	move	through	configuration	items.

Whether the system will work stably with the overclock/overvoltage settings you made is dependent on your overall system	configurations.	 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 v\
alues and reset the board to default values.)
