Revision 1.40
to place the system in the On state. The OS retains control of the system and OS policy
determines the sleep state, if any, and the sleep sources from which the system can wake.
6.3.3
Wired For Management (WFM)
Wired for Management (WFM) is an industry-wide initiative to increase overall manageability and
reduce the total cost of ownership. WFM allows a server to be managed over a network. The
system BIOS supports revision 2.0 of the
Wired For Management Baseline Specification
. It also
supports the pre-boot execution environment, as outlined in the WFM baseline specification, if
the system includes an embedded WFM compliant network device.
The system BIOS supports version 2.3.1 of the
System Management BIOS Reference
Specification
to help higher-level instrumentation software meet the WFM requirements. The
higher level software can use the information provided by the system management (SM)BIOS to
instrument desktop management interface (DMI) standard groups that are specified in the WFM
specification.
The BIOS also configures the SYSID table as described in the
Network PC System Design
Guidelines, Revision 1.0
. This table contains the globally unique ID (GUID) of the baseboard. The
mechanism that sets the GUID in the factory is defined in the
SYSID BIOS Support Interface
Requirement Specification, Version 1.2
. The caller must provide the correct security key for this
call to succeed.
When in S4/S5 mode, PCI device can use PME(Power Management Event)# signal to wake up
the Machine. It's an essential element in ACPI.
6.3.3.1
PXE BIOS Support
This section discusses host system BIOS support required for PXE compliance and how PXE
boot devices (ROMs) and PXE Network Boot Programs (NBPs) use it.
6.3.3.2
BIOS Requirements
PXE-compliant BIOS implementations must
:
•
Locate and configure all PXE-capable boot devices (UNDI Option ROMs) in the system,
both built-in and add-ins.
•
Supply a PXE according to this specification if the system includes a built-in network
device.
•
Implement the following specifications:
•
Plug-and-Play BIOS Specification v1.0a or later.
•
System Management BIOS (SMBIOS) Reference Specification v2.2 or later.
•
The requirements defined in Sections 3 and 4 of the BIOS Boot Specification (BBS)
v1.01or later, to support network adapters as boot devices.
•
Supply a valid UUID and Wake-up Source value for the system via the SMBIOS structure
table
.
