Boot Features
Quick Boot: Skip certain tests during POST to reduce the time needed for system boot.

AddOn ROM Display Mode: Sets the display mode for Option ROM.
Bootup Num-Lock: Selects the Power-on state for Numlock key.
Wait For 'F1' If Error: Forces the system to wait until the <F1> key is pressed if an error occurs.
Interrupt 19 Capture: Interrupt 19 is the software interrupt that handles the boot disk function. When this item
is set to Enabled, the ROM BIOS of the host adaptors will capture Interrupt 19 at boot and allow the drives that
are attached to these host adaptors to function as bootable disks. If this item is set to Disabled, the ROM
BIOS of the host adaptors will not capture Interrupt 19, and the drives attached to these adaptors will not
function as bootable devices.
Power configuration
Power Button Function: If set to Instant_Off, the system will power off immediately when you press the
power button. If set to 4_Second_Override, the system will power off when you press the power button for four
seconds or longer.
Restore on AC Power Loss: Use this feature to set the power state after a power outage. Select Power-Off
for the system power to remain off after a power loss. Select Power-On for the system power to be turned on
after a power loss. Select Last State to allow the system to resume its last state before a power loss.
Watch Dog Timer: If enabled, the Watch Dog Timer will allow the system to reboot when it is inactive for more
than five minutes.
Processor & Clock Options
This submenu displays the status of the processor as detected by the BIOS, including items such as the
processor manufacturer, type, frequency, CPUID, Microcode Revision, Cache L1/L2/L3, Ratio Status, and
Ratio Actual Value. The submenu also allows you to configure the processor and clock settings.
Ratio CMOS Setting: This option allows you to set the ratio between the CPU core clock and the FSB
frequency.The default setting depends on the type of CPU installed on the motherboard. The default setting for
the CPU installed in your motherboard is [18]. Press "+" or "-" on your keyboard to change this value.
NOTE: if an invalid ratio is entered, the BIOS will restore the setting to the previous state.
C1E Support: Select Enabled to use the feature of Enhanced Halt State. C1E significantly reduces the CPU's
power consumption by reducing the CPU's clock cycle and voltage during a Halt State.
Important: The following feature is only available if supported by the processor and/or operating system.
Hardware Prefetcher: If set to Enabled, the hardware prefetcher will prefetch streams of data and
instructions from the main memory to the L2 cache in the forward or backward manner to improve CPU
performance.
IMPORTANT:Important: The following feature is only available if supported by the processor and/or operating
system.
Adjacent Cache Line Prefetch: The CPU fetches the cache line for 64 bytes if this option is set to Disabled.
The CPU fetches both cache lines for 128 bytes as comprised if Enabled.
MPS and ACPI MADT Ordering: Allows you to configure the MPS (Multi-Processor Specifi cations) and ACPI
