Prmary Graphc’s Adapter
Ths settng specfies whch graphc card s your prmary graphcs adapter.
PCI Latency Tmer
Ths tem controls how long each PCI devce can hold the bus before another takes
over. When set to hgher values, every PCI devce can conduct transactons for a longer
tme and thus mprove the effectve PCI bandwdth. For better PCI performance, you
should set the tem to hgher values.
CPU Feature
Press <Enter> to enter the sub-menu and the followng screen appears:
Hyper-Threadng Functon
The processor uses Hyper-Threadng technology to ncrease transacton rates and
reduces end-user response tmes. The technology treats the two cores nsde the
processor as two logcal processors that can execute nstructons smultaneously. In
ths way, the system performance s hghly mproved. If you dsable the functon, the
processor wll use only one core to execute the nstructons. Please dsable ths tem
f your operatng system doesn’t support HT Functon, or unrelablty and nstablty
may occur.
Execute Bt Support
Intel’s Execute Dsable Bt functonalty can prevent certan classes of malcous
“buffer overflow” attacks when combned wth a supportng operatng system. Ths
functonalty allows the processor to classfy areas n memory by where applcaton
code can execute and where t cannot. When a malcous worm attempts to nsert
code n the buffer, the processor dsables code executon, preventng damage or
worm propagaton.
C1E Support
To enable ths tem to read the CPU power consumpton whle dle. Not all proces-
sors support Enhanced Halt state (C1E).
Overspeed Protecton
Ths tem s used to enable/ dsable Overspeed Protecton.
