IOAPIC Functon
Ths 󰘰eld 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 󰘰eld allows you to select whch MPS (Mult-Processor Spec󰘰cat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 󰘰nd 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󰘰es 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 e󰘯ect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:
Execute Bt Support
Intel’s Execute Dsable Bt functonalty can prevent certan classes of malcous
“bu󰘯er over󰘱ow” attacks when combned wth a supportng operatng system. Ths
functonalty allows the processor to classfy areas n memory by where applcaton
code can execute and where t cannot. When a malcous worm attempts to nsert
code n the bu󰘯er, the processor dsables code executon, preventng damage or
worm propagaton.
Set Lmt CPUID MaxVal to 3
The Max CPUID Value Lmt s desgned lmt the lsted speed of the processor to
older operatng systems.
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).
