3. 64-bit Mode: 64-bit operating system and 64-bit applications. This usage requires 64-bit device drivers.
It also requires applications to be modified for 64-bit operation and then recompiled and validated.
Intel 64 provides support for:
64-bit flat virtual address space
64-bit pointers
64-bit wide general purpose registers
64-bit integer support
Up to one Terabyte (TB) of platform address space

Virtualization Technology
Virtualization solutions enhanced by Intel VT will allow a Core Duo and Core 2 Duo platform to run
multiple operating systems and applications in independent partitions. When using virtualization
capabilities, one computer system can function as multiple "virtual" systems. With processor and I/O
enhancements to Intel's various platforms, Intel Virtualization Technology can improve the performance and
robustness of today's software-only virtual machine solutions.
Intel VT is a multi-generational series of extensions to Intel processor and platform architecture that
provides a new hardware foundation for virtualization, establishing a common infrastructure for all classes
of Intel based systems. The broad availability of Intel VT makes it possible to create entirely new
applications for virtualization in servers, clients as well as embedded systems thus providing new ways to
improve system reliability, manageability, security, and real-time quality of service.
The success of any new hardware architecture is highly dependent on the system software that puts its new
features to use. In the case of virtualization technology, that support comes from the virtual machine monitor
(VMM), a layer of software that controls the underlying physical platform resources sharing them between
multiple "guest" operating systems. Intel VT is already incorporated into most commercial and open-source
VMMs including those from VMware, Microsoft, XenSource, Parallels, Virtual Iron, Jaluna and TenAsys.

Thermal Management
ACPI is responsible for allowing the operating system to play an important part in the system's thermal
management. This results in the operating system having the ability to take control of the operating
environment by implementing cooling decisions according to the demands put on the CPU by the
application.
The COM 830 ACPI thermal solution offers three different cooling policies.
Passive Cooling
When the temperature in the thermal zone must be reduced, the operating system can decrease the power
consumption of the processor by throttling the processor clock. One of the advantages of this cooling policy
is that passive cooling devices (in this case the processor) do not produce any noise. Use the “passive
cooling trip point” setup node in the BIOS setup program to determine the temperature threshold that the
operating system will use to start or stop the passive cooling procedure.
NOTE Ampro does not intend to offer BSPs for 64-bit operating systems. Contact
technical support if you plan to use a 64-bit operating system on the COM 830.
NOTE Ampro does not offer virtual machine monitor (VMM) software. All VMM
software support questions and queries should be directed to the VMM software
vendor and not technical support.
