Execute Disable Bit
Intel’s Execute Disable Bit functionality can prevent certain classes of mali-
cious “buffer over
fl
ow” attacks when combined with a supporting operating
system. This functionality allows the processor to classify areas in memory
by where application code can execute and where it cannot. When a mali-
cious worm attempts to insert code in the buffer, the processor disables
code execution, preventing damage or worm propagation.

Intel Virtualization Technology
Virtualization enhanced by Intel Virtualization Technology will allow a plat-
form to run multiple operating systems and applications in independent
partitions. With virtualization, one computer system can function as mul-
tiple “virtual” systems.

EIST
EIST (Enhanced Intel SpeedStep Technology) allows the system to dy-
namically adjust processor voltage and core frequency, which can result
in decreased average power consumption and decreased average heat
production.

Turbo Mode
Intel Turbo Memory is a new Intel platform technology that uses non-vola-
tile memory (Flash memory) to increase system responsiveness, make
multi-tasking faster, and extend battery life. This technology is poised to
eliminate many of the bottlenecks associated with HDD latency. By en-
abling the majority of application workload to be written and read from
a system cache instead of the HDD, Turbo Memory will offer users sig-
ni
fi
cantly increased performance -- particularly in application load and run
time, the speed in which systems resume operation after hibernation or
boot, and in system-level power usage.
