Briefly, system and method for message-based power management which may be used, for example, in computer systems and communications networks. Embodiments of the present invention may include, for example, a device connected to a power management controller (PMC); the device and/or the PMC may send, receive, and/or process power management event (PME) messages. Embodiments of the present invention may operate using links in communicative and/or non-communicative modes. Embodiments of the present invention may include a switch, to send/receive, process, create, re-format and/or route one or more PME message on behalf of various devices, for example, a Peripheral Component Interconnect (PCI) device.

A non-volatile random access memory (NVRAM) is used in a computer system to store information that allows the NVRAM to autonomously initialize itself at power-on. The computer system includes a processor, an NVRAM controller coupled to the processor, and an NVRAM that comprises the NVRAM controller. The NVRAM is byte-rewritable and byte-erasable by the processor. The NVRAM stores a memory interface table containing information for the NVRAM controller to autonomously initialize the NVRAM upon power-on of the computer system without interacting with the processor and firmware outside of the NVRAM. The information is provided by the NVRAM controller to the processor to allow the processor to access the NVRAM.

A non-volatile random access memory (NVRAM) is used in a computer system to perform multiple roles in the platform storage hierarchy. The NVRAM is byte-rewritable and byte-erasable by the processor. The NVRAM is coupled to the processor to be directly accessed by the processor without going through an I/O subsystem. The NVRAM stores a Basic Input and Output System (BIOS). During a Pre-Extensible Firmware Interface (PEI) phase of the boot process, the cache within the processor can be used in a write-back mode for execution of the BIOS.

Hot plug modules comprising processors, memory, and/or I/O hubs may be added to and removed from a running computing device without rebooting the running computing device. The hot plug modules and computing device comprise hot plug interfaces that support hot plug addition and hot plug removal of the hot plug modules.

An apparatus and system may include a peripheral device, such as an interrupt controller or Peripheral Component Interconnect (PCI) bridge device, having a memory-mapped legacy register and a PCI dummy register. The legacy register may be accessed by a Basic Input/Output System (BIOS) as part of a power-on initialization sequence for the peripheral device, and the dummy register may be accessed during a hot-plug operation using code executed by an Operating System (OS). An article, including a machine-accessible medium, may contain data capable of causing a machine to carry out a method of representing a peripheral device which includes identifying the peripheral device as a legacy device in a name space, such as an Advanced Configuration and Power Interface (ACPI) name space, and identifying the peripheral device as a dummy PCI device capable of being accessed during a hot-plug operation.

A 'Plug and Play' type dynamic detection and binding capability for wireless peripheral devices is disclosed. The dynamic detection and binding of wireless peripherals is achieved without manual intervention, and without modifications to the host computing device's built-in operation system (BIOS). Dynamic detection and binding of a wireless peripheral device by a host is accomplished by transmitting a Device_Hail message (405), waiting for a Hail_Response message (425) from a peripheral, and, upon the reception of a Hail_Response message (425), assigning a Peripheral Address to the responding peripheral and transmitting it to the peripheral in a Peripheral_Address_Allocation message (430).
