► APIC Mode (Advanced Programmable Interrupt Controller)
This item is used to enable or disable APIC function.
APIC interrupt subsystems can have as many IRQs as are required in a specic machine.
APICs are benecial for the following reasons :
• APICs can contribute to resolving resource conicts in the PC platform.
• Windows operating systems have been designed with APICs in mind.
• APICs are necessary for enabling new features in the PCI specication.
► MPS Version Control For OS (Multi-Processor Specication)
This feature is only applicable to multiprocessor motherboards as it species the version of the
MPS that the motherboard will use. The MPS is a specication by which PC manufacturers
design and build Intel architecture systems with two or more processors. MPS 1.1 was the
original specication. MPS version 1.4 adds extended conguration tables for improved
support of multiple PCI bus congurations and greater expandability in the future. In addition,
MPS 1.4 introduces support for a secondary PCI bus without requiring a PCI bridge.
If your operating system comes with support for MPS 1.4, you should keep the setting as
the default 1.4. You also need to enable MPS 1.4 support if you need to make use of the
secondary PCI bus on a motherboard that doesn't come with a PCI bridge.
You should only leave it as 1.1 only if you are running an older operating system that only
supports MPS 1.1.
