BIOS Setup

Wait For ‘F1’ If Error

When this setting is set to [Enabled] and the boot sequence encounters

an error, it asks you to press F1. If disabled, the system continues to boot

without waiting for you to press any keys.

CPU Configuration

Ratio CMOS Setting

This setting controls the multiplier that is used to determine the internal

clock speed of the processor relative to the external or motherboard

clock speed.

Execute Disable Bit Capability

Intel’s Execute Disable Bit functionality can prevent certain classes of

malicious “buffer overflow” attacks when combined with a supporting

operating system. This functionality allows the processor to classify

areas in memory by where application code can execute and where it

cannot. When a malicious worm attempts to insert code in the buffer,

the processor disables code execution, preventing damage or worm

propagation.

Intel(R) SpeedStep(tm) Tech

EIST (Enhanced Intel SpeedStep Technology) allows the system to

dynamically adjust processor voltage and core frequency, which can

result in decreased average power consumption and decreased aver-

age heat production.
