CHAPTER 2
BIOS SETUP
The primary function of the BIOS (Basic Input and Output System) is to identify and initiate component
hardware. The BIOS parameters are stored in non-volatile BIOS memory (CMOS). CMOS contents don’t get
erased when the computer is turned off. The following topics are described in this chapter.
• About the Setup Utility on page 5
• Main Screen on page 8
• OC Tweaker on page 9
• Advanced Settings on page 10
• H/W Monitor on page 19
• Boot Settings on page 20
• Security Settings on page 22
• Exit Menu on page 23
About the Setup Utility
The BIOS Setup Utility enables you to congure the following items:
• Hard drives, diskette drives, and peripherals
• Video display type and display options
• Password protection from unauthorized use
• Power management features
This Setup Utility should be used for the following:
• When changing the system conguration
• When a conguration error is detected and you are prompted to make changes to the Setup Utility
• When trying to resolve IRQ conicts
• When making changes to the Power Management conguration
• When changing the User or Supervisor password

6 CHAPTER 2 BIOS SETUP
Entering the Setup Utility
When you power on the system, BIOS enters the Power-On Self Test (POST) routines. POST is a series of
built-in diagnostics performed by the BIOS. After the POST routines are completed, the following message
appears:
Press F2 or DEL to run Setup
Press the delete key <Delete> to access the BIOS Setup Utility:
BIOS navigation keys
The BIOS navigation keys are listed below.
Key Function
← → Select screens
↑ ↓ Select items
+ – Modify the selected eld’s values
Enter Go to sub screen
F1 Display a screen that describes all key functions
F9 Load the default settings
F10 Save the current conguration and exit BIOS setup.
Esc Exit the current screen

Using BIOS
When you start the Setup Utility, the main screen appears. The main screen of the Setup Utility displays a list
of the options that are available. A highlight indicates which option is currently selected. Use the cursor arrow
keys to move the highlight to other options. When an option is highlighted, execute the option by pressing
<Enter>.
Some options lead to pop-up dialog boxes that prompt you to verify that you wish to execute that option.
Other options lead to dialog boxes that prompt you for information.
Some options (marked with a triangle ►) lead to sub screens that enable you to change the values for the
option. Use the cursor arrow keys to scroll through the items in the sub screen.

8 CHAPTER 2 BIOS SETUP
Main Screen
This screen includes System BIOS Information, Processor, System memory and displays the System Time
and System Date.
System Overview
This screen displays System BIOS Information, Processor, System memory, System Time and System Date.
System Time/ System Date
The System Time and System Date items show the current date and time held by the machine. If you are
running a Windows OS, these items are automatically updated whenever you make changes to the Windows
Time and Date Properties utility.

Screen
OC Tweaker
In the OC Tweaker screen, you can set up overclocking features.
Boot Failure Guard
Boot Failure Guard is a boot failure restore feature. While system could not bootup normally at overclocking
setting, the safe boot up mode will be issue from Boot Failure Guard and provide a BIOS setting Interface to
parameter reset/correction. This item is used to enable/disable the feature of Boot Failure Guard.
Boot Failure Guard Count
This item is used to enable/disable the feature of Boot Failure Guard Count.
Would you like to save current setting as user defaults?
You can load and save three user defaults according to your own requirements.

10 CHAPTER 2 BIOS SETUP
Advanced Settings
This setup screen includes sub-menus for CPU Conguration, Chipset Conguration, ACPI Congurations,
Storage Congurations, PCIPnP Congurations, SuperIO Congurations and USB Congurations.
ASRock Instant Flash
This item is used to execute the BIOS update utility. The utility can search BIOS les in USB and hard disk
drive automatically for updating.

12 CHAPTER 2 BIOS SETUP
Primary Graphics Adapter
This item species which graphics card is your primary graphics adapter.
DVMT Mode Select
Intel’s Dynamic Video Memory Technology (DVMT) allows the system to dynamically allocate memory
resources according to the demands of the system at any point in time. The key idea in DVMT is to improve
the efciency of the memory allocated to either system or graphics processor. It is recommended that you set
this BIOS feature to DVMT Mode for maximum performance. Setting it to DVMT Mode ensures that system
memory is dynamically allocated for optimal balance between graphics and system performance.
DVMT/FIXED Memory
When set to DVMT/FIXED Mode, the graphics driver will allocate a xed amount of memory as dedicated
graphics memory, as well as allow more system memory to be dynamically allocated between the graphics
processor and the operating system.
Flat Panel Type
This item allows you to select the type of at panel monitor.
Onboard HD Audio
This item allows you to enable or disable the onboard HD Audio feature. If you select [Auto], the onboard
HD Audio will be disabled when PCI Sound Card is plugged.
Onboard LAN
This item allows you to enable or disable the built-in LAN port.
