HDD S.M.A.R.T Capability
This allows you to activate the S.M.A.R.T. (Self-Monitoring Analysis & Reporting
Technology) capability for the hard disks. S.M.A.R.T is a utility that monitors your
disk status to predict hard disk failure. This gives you an opportunity to move
data from a hard disk that is going to fail to a safe place before the hard disk
becomes offline. Settings:
Enabled
and
Disabled
.
HT CPU Function
The Intel processor uses Hyper-Threading technology to increase transaction rates
and reduces end-user response times. The technology treats the two cores inside
the processor as two logical processors that can execute instructions
simultaneously. In this way, the system performance is highly improved. If you
disable the function, the processor will use only one core to execute the
instructions. Settings:
Enabled
and
Disabled
.
APIC Mode
This field is used to enable or disable the APIC (Advanced Programmable Inter-
rupt Controller). Due to compliance with PC2001 design guide, the system is
able to run in APIC mode. Enabling APIC mode will expand available IRQ re-
sources for the system. Settings:
Enabled
and
Disabled
.
