Intel® Server Board SE7320VP2
4.8
The IPMI 1.5 specification, section 22.10 and 22.11, has provisions for server management
devices to set certain boot parameters by setting boot flags. Among the boot flags, parameter
#5 in the IPMI specification, the BIOS checks data 1-3 for forced boot options.
The BIOS supports force boots from: PXE, HDD, FDD, and CD.
On each boot, the BIOS determines what changes to boot options have been set by invoking
the Get System Boot Options command, takes appropriate action, and clears these settings.

Intel Corporation and Microsoft Corporation co-author design guides for system designers using
Intel
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 one used for enterprise applications.
The BIOS supports HDG 3.0.
4.8.2
The BIOS is ACPI 2.0c-compliant. The primary role of the BIOS is to provide ACPI tables.
During POST, the BIOS creates the ACPI tables and locates them in extended memory (above
1MB). The location of these tables is conveyed to the ACPI-aware operating system through a
series of tables located throughout memory. The format and location of these tables is
documented in the publicly available ACPI specification.
To prevent conflicts with a non-ACPI-aware operating system, the memory used for the ACPI
tables is marked as “reserved”.
As described in the ACPI specification, an ACPI-aware operating system generates an SMI to
request that the system be switched into ACPI mode. The BIOS responds by setting up all
system (chipset) specific configuration required to support ACPI, and sets the SCI_EN bit as
defined by the ACPI specification. The system automatically returns to legacy mode on hard
reset or power-on reset.
The BIOS supports S0, S1, S4, and S5 states. S1 and S4 are considered sleep states. The
ACPI specification defines the sleep states and requires the system to support at least one of
them.
While entering the S4 state, the operating system saves the context to the disk and most of the
system is powered off. The system can wake on a power button press, or a signal received from
a wake-on-LAN compliant LAN card (or onboard LAN), modem ring, PCI power management
