Chapter 3: BIOS Setup Utility
Spread Spectrum
If you enable spread spertrum, it can significantly reduce the EMI (Electro-
Magnetic interface) generated by the system.
Hyper-Threading Technology
You can set “Disabled” or “Enabled” to control HT CPU support in O.S. Set
“Enabled” to test HT CPU function.
Max CPUID Value Limit
You can use Prescott CPU and LGA-775 CPU when this item is enabled, and
there will be a normal NT4.0 installation; otherwise, the automatic restarting will
occur while installing.
DRAM Driving
The default value is “Normal”. If the system is unstable while using some DDR
SDRAMs, you may select “High” option.
Execute Disable Bit
It 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. Replacing older computers with Execute Disable Bit-enabled
systems can halt worm attacks, reducing the need for virus related repairs.
