cessor and the main memory. Located away from the CPU, the L3 cache is slower than the L1 & L2 caches. This setting allows you to turn on or off the L3 cache.
Hyper-Threading Technology
The processor uses Hyper-Threading technology to increase transaction rates and reduces end-user response times. The technology treats the two cores inside the processor as two logical processors that can execute instructions simultaneously. In this way, the system performance is highly improved. If you disable the function, the processor will use only one core to execute the instructions. Please disable this item if your operating system doesn’t support HT Function, or unreliability and instability may occur.
Important
Enabling the functionality of Hyper-Threading Technology for your computer system requires ALL of the following platform Components:
*CPU: An Intel® Pentium® 4 Processor with HT Technology;
*Chipset: An Intel® Chipset that supports HT Technology;
*BIOS: A BIOS that supports HT Technology and has it enabled;
*OS: An operating system that supports HT Technology.

Quick Power On Self Test
Select [Enabled] to reduce the amount of time required to run the power-on self- test (POST). A quick POST skips certain steps. We recommend that you nor- mally disable quick POST. Better to find a problem during POST than lose data during your work.
APIC Mode
This field is used to enable or disable the APIC (Advanced Programmable Inter- rupt Controller). Due to compliance with PC2001 design guide, the system is able to run in APIC mode. Enabling APIC mode will expand available IRQ re- sources for the system.
MPS Version Control For OS
This field allows you to select which MPS (Multi-Processor Specification) ver- sion to be used for the operating system. You need to select the MPS version supported by your operating system. To find out which version to use, consult the vendor of your operating system.
