▶ 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 Technology
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.
Important
Enablng the functonalty of Hyper-Threadng Technology for your computer system
requres ALL of the followng platform Components:
• CPU: An Intel Pentum
®
• Chpset: An Intel
• BIOS: A BIOS that supports HT Technology and has t enabled;
OS: An operatng system that supports HT Technology.

▶ 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.
▶ Set Lmt CPUID MaxVal to 3
The Max CPUID Value Lmt s desgned lmt the lsted speed of the processor to
older operatng systems.
