▍ BIOS Setup ▶ IOAPIC Function This field is used to enable or disable the APIC (Advanced Programmable Interrupt Controller). Due to compliance with PC2001 design guide, the system is able to run in APIC mode. Enabling APIC mode will expand available IRQ resources for the system. ▶ MPS Table Version This field allows you to select which MPS (Multi-Processor Specification) version 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. ▶ Primary Graphic's Adapter This setting specifies which graphic card is your primary graphics adapter. ▶ PCI Latency Timer This item controls how long each PCI device can hold the bus before another takes over. When set to higher values, every PCI device can conduct transactions for a longer time and thus improve the effective PCI bandwidth. For better PCI performance, you should set the item to higher values. ▶ CPU Feature Press to enter the sub-menu and the following screen appears: ▶ SVM Support This item is used to enable/ disable SVM. ▶ C1E Support To enable this item to read the CPU power consumption while idle. Not all processors support Enhanced Halt state (C1E). ▶ Chipset Feature Press to enter the sub-menu and the following screen appears: ▶ HPET The HPET (High Precision Event Timers) is a component that is part of the chipset. You can to enable it, and will provide you with the means to get to it via the various ACPI methods. 3-10

BIOS Setup
▍
IOAPIC Funct±on
Th±s field ±s used to enable or d±sable the APIC (Advanced Programmable Interrupt
Controller). Due to compl±ance w±th PC2001 des±gn gu±de, the system ±s able to run ±n
APIC mode. Enabl±ng APIC mode w±ll expand ava±lable IRQ resources for the system.
MPS Table Vers±on
Th±s field allows you to select wh±ch MPS (Mult±-Processor Spec±ficat±on) vers±on to be
used for the operat±ng system. You need to select the MPS vers±on supported by your
operat±ng system. To find out wh±ch vers±on to use, consult the vendor of your operat±ng
system.
Pr±mary Graph±c’s Adapter
Th±s sett±ng spec±fies wh±ch graph±c card ±s your pr±mary graph±cs adapter.
PCI Latency T±mer
Th±s ±tem controls how long each PCI dev±ce can hold the bus before another takes
over. When set to h±gher values, every PCI dev±ce can conduct transact±ons for a longer
t±me and thus ±mprove the effect±ve PCI bandw±dth. For better PCI performance, you
should set the ±tem to h±gher values.
CPU Feature
Press <Enter> to enter the sub-menu and the follow±ng screen appears:
SVM Support
Th±s ±tem ±s used to enable/ d±sable SVM.
C1E Support
To enable th±s ±tem to read the CPU power consumpt±on wh±le ±dle. Not all proces-
sors support Enhanced Halt state (C1E).
Ch±pset Feature
Press <Enter> to enter the sub-menu and the follow±ng screen appears:
HPET
The HPET (H±gh Prec±s±on Event T±mers) ±s a component that ±s part of the ch±pset.
You can to enable ±t, and w±ll prov±de you w±th the means to get to ±t v±a the var±ous
ACPI methods.
