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.
