CPU Configuration

Hyper-Threading
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 Disable Bit
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.
▶
Limit CPUID Maximum
The Max CPUID Value Lmt BIOS feature allows you to crcumvent problems
wth older operatng systems that do not support the Intel Pentum 4 processor
wth Hyper-Threadng Technology. When enabled, the processor wll lmt the
maxmum CPUID nput value to 03h when quered, even f the processor
supports a hgher CPUID nput value. When dsabled, the processor wll return
the actual maxmum CPUID nput value of the processor when quered.
