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 allows the user to modify basic system configuration settings or to activate certain system features.
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 configurations. Incorrectly doing overclock/overvoltage may result in damage to CPU, chipset, or memory and reduce the useful life of these components.
&& CPU PLL Selection Allows you to set the CPU PLL. Auto lets the BIOS automatically configure this setting. (Default: Auto) && Filter PLL Level Allows you to set the Filter PLL. Auto lets the BIOS automatically configure this setting. (Default: Auto) && Uncore Ratio Allows you to set the CPU Uncore ratio. The adjustable range is dependent on the CPU being used. && Uncore Frequency Displays the current CPU Uncore frequency.
&& CPU Thermal Monitor (Note 1) Enables or disables Intel® Thermal Monitor function, a CPU overheating protection function. When enabled, the CPU core frequency and voltage will be reduced when the CPU is overheated. Auto lets the BIOS automatically configure this setting. (Default: Auto) && CPU EIST Function (Note 1) Enables or disables Enhanced Intel® Speed Step Technology (EIST).
&& Profile DDR Voltage When using a non-XMP memory module or Extreme Memory Profile (X.M.P.) is set to Disabled, the valueis displayed according to your memory specification. When Extreme Memory Profile (X.M.P.) is set to Profile1 or Profile2, this item will display the value based on the SPD data on the XMP memory. && Channel Interleaving Enables or disables memory channel interleaving.
&& CPU Fan Speed Control Allows you to determine whether to enable the fan speed control function and adjust the fan speed. Normal Allows the fan to run at different speeds according to the CPU temperature. You can adjust the fan speed with System Information Viewer based on your system requirements. (Default) Silent Allows the fan to run at slow speeds. Manual Allows you to control the fan speed under the Fan Speed Percentage item. Full Speed Allows the fan to run at full speeds.
2-3 System Information This section provides information on your motherboard model and BIOS version. You can also select the default language used by the BIOS and manually set the system time. && System Language Selects the default language used by the BIOS. && System Date Sets the system date. The date format is week (read-only), month, date, and year. Use to switch between the Month, Date, and Year fields and use the or key to set the desired value.
2-4 BIOS Features && Boot Option Priorities Specifies the overall boot order from the available devices. For example, you can set hard drive as the first priority (Boot Option #1) and DVD ROM drive as the second priority (Boot Option #2). The list only displays the device with the highest priority for a specific type. For example, only hard drive defined as the first priority on the Hard Drive BBS Priorities submenu will be presented here.
&& VGA Support Allows you to select which type of operating system to boot. Auto Enables legacy option ROM only. EFI Driver Enables EFI option ROM. (Default) This item is configurable only when Fast Boot is set to Enabled or Ultra Fast. && USB Support Disabled All USB devices are disabled before the OS boot process completes. Full Initial All USB devices are functional in the operating system and during the POST.
Never Disables UEFI CSM and supports UEFI BIOS boot process only. This item is configurable only when Windows 8 Features is set to Windows 8 or Windows 8 WHQL. && Boot Mode Selection Allows you to select which type of operating system to boot. UEFI and Legacy Allows booting from operating systems that support legacy option ROM or UEFI option ROM. (Default) Legacy Only Allows booting from operating systems that only support legacy Option ROM.
2-5 Peripherals && Initial Display Output Specifies the first initiation of the monitor display from the installed PCI Express graphics card or the onboard graphics. IGFX Sets the onboard graphics as the first display. PCIe 1 Slot Sets the graphics card on the PCIEX16 slot as the first display. (Default) && XHCI Mode Allows you to determine the operating mode for the xHCI controller in OS.
&& Audio Controller Enables or disables the onboard audio function. (Default: Auto) If you wish to install a 3rd party add-in audio card instead of using the onboard audio, set this item to Disabled. && Intel Processor Graphics Enables or disables the onboard graphics function. (Default: Enabled) && Intel Processor Graphics Memory Allocation Allows you to set the onboard graphics memory size. Options are: 32M~1024M.
`` Super IO Configuration This section provides information on the super I/O chip and allows you to configure the serial port and parallel port. && Serial Port A Enables or disables the onboard serial port. (Default: Enabled) && Parallel Port Enables or disables the onboard parallel port. (Default: Enabled) && Device Mode This item is configurable only when Parallel Port is set to Enabled. Selects an operating mode for the onboard parallel (LPT) port.
2-6 Power Management && Power Loading Enables or disables dummy load. When the power supply is at low load, a self-protection will activate causing it to shutdown or fail. If this occurs, please set to Enabled. Auto lets the BIOS automatically configure this setting. (Default: Auto) && Resume by Alarm Determines whether to power on the system at a desired time.
&& Power On By Keyboard Allows the system to be turned on by a PS/2 keyboard wake-up event. Note: To use this function, you need an ATX power supply providing at least 1A on the +5VSB lead. Disabled Disables this function. (Default) Password Set a password with 1~5 characters to turn on the system. Keyboard 98 Press POWER button on the Windows 98 keyboard to turn on the system. Any Key Press any key to turn on the system.
&& Exit Without Saving Press on this item and select Yes. This exits the BIOS Setup without saving the changes made in BIOS Setup to the CMOS. Select No or press to return to the BIOS Setup Main Menu. && Load Optimized Defaults Press on this item and select Yes to load the optimal BIOS default settings. The BIOS defaults settings help the system to operate in optimum state. Always load the Optimized defaults after updating the BIOS or after clearing the CMOS values.
