4.9.1
Microsoft* Windows* Compatibility
Intel Corporation and Microsoft Corporation co-author design guides for system designers using
Intel processors and Microsoft* operating systems. These documents are updated yearly to
address new requirements and current trends.
PC200x specifications are intended for systems that are designed to work with Windows 2000
and Windows XP class operating systems. The Hardware Design Guide (HDG) for the Windows
XP platform is intended for systems that are designed to work with Windows XP class operating
systems. Each specification classifies the systems further and has requirements based on the
intended usage for that system. For example, a server system that will be used in small
home/office environments has different requirements than the one used for enterprise
applications.
The server board SE7210TP1-E supports HDG3.0.
4.9.2
Advanced Configuration and Power Interface (ACPI)
ACPI gives the operating system direct control over the power management and Plug and Play
functions of a server. The use of ACPI with the Intel Server Board SE7210TP1-E requires an
operating system that provides full ACPI support. ACPI features include:
• Plug and Play (including bus and device enumeration)
• Power management control of individual devices, add-in boards (some add-in boards
may require an ACPI-aware driver), video displays, and hard disk drives
• Methods for achieving less than 15-watt system operation in the standby or
sleeping state
• A Soft-off feature that enables the operating system to power-off the server
• Support for multiple wake-up events.
• Support for a front panel power and sleep mode switch
4.9.3
Sleep and Wake Functionality
The BIOS supports up to four front panel buttons: the power button, the reset button, the sleep
button, and the NMI button. The NMI button is a recessed button and may not be accessible on
all front panel designs.
The power button is a request that is forwarded by the National Semiconductor PC87431
integrated management controller to the ACPI power state machines in the chipset. It is
monitored by the National Semiconductor PC87431 integrated management controller and does
not directly control power on the power supply.
The BIOS supports a front panel NMI button. The NMI button is a request that causes the
National Semiconductor PC87431 integrated management controller to generate an NMI (non-
maskable interrupt). The operating system is responsible for handling the NMI core dump.
The power button behaves differently depending on whether the operating system supports
ACPI. If the operating system supports ACPI the power button can be configured as a sleep
