摘要:
A plurality of instructions corresponding to a power management event are received. An instruction of the plurality of instructions is executed in a first programming system with a first interface, in response to determining that the instruction is in accordance with the first interface. The instruction is executed in a second programming system with a second interface, in response to determining that the instruction is not in accordance with the first interface.

The present disclosure is directed to flexible bootstrap code architecture. A device may comprise equipment for operating the device and an operating system (OS) for operating the equipment A boor, module may also be included in the device to execute boot operations. At least one flexible boot (FB) module in the boot module may interact with the equipment and/or OS during the boot operations to cause the boot operations to become device-specific. An example boot module may comprise a plurality of FB modules. An example FB module may verify a device/chipset identification and may control the boot operations based on the identification. Other example FB modules may select resources to load based on an OS type, may provide a boot configuration table location for use in OS runtime boot configuration or may load variables from a preload variable directory for use in configuring boot operations.

In some embodiments, the invention involves system and method for resuming from sleep mode using protected storage accessible to an embedded controller. The boot script information is stored in memory that is available only to the embedded controller. Neither the firmware nor OS have access to the boot script. Upon a wake event, the embedded controller either plays the boot script itself, or sends the information to firmware for processing. Other embodiments are described and claimed.

Provided are a method, system and program for effecting a processor operating mode change to execute device code. A processor receives a call while the processor is operating in a first mode, wherein the call is made to effect execution of device code to control a device. The processor determines whether the call is intended to change a processor operating mode from the first mode to a second mode. The state of the processor is selectively changed to a second mode in which the processor executes second mode instructions loaded in a protected section of memory inaccessible to an operating system in response to determining that the call is intended to change the processor operating mode. The second mode instructions execute the device code to control the device.

Methods and apparatus for remotely managing a computer are disclosed. For example, a remote management agent is provided for use in a computer having a processor. The example remote management agent includes a communication agent in communication with the controller to contact a server before an operating system is loaded on the computer to obtain an initialization packet from a server and an initialization packet loader in communication with the controller to load the initialization packet in a protected memory area of the computer, before the operating system is loaded.The remote management agent also includes a monitoring agent, not associated with the operating system, in communication with the controller to monitor the computer for a communication from the server and a command line interface agent, also not associated with the operating system and in communication with the controller to interpret and respond to the communication from the server.
摘要:
A keyboard, video, mouse switch may be implemented by software. An agent in a sequestered partition may handle routing of input and output requests for handling by a remote, common, keyboard, video, or mouse used for a plurality of servers.

In some embodiments, the invention involves a system and method relating to autonomic boot recovery. In at least one embodiment, the present invention utilizes an out-of-band (OOB) microcontroller to safeguard boot information to be used in the event of a boot failure. The OOB microcontroller enables the preservation of “Last Known Good” boot configurations as well as providing an agent to provide self-healing to a platform which might have run into some type of corruption of critical data. In some embodiments a variety of intelligent filter mechanisms are enabled to allow a user to target the preservation of only certain types of configuration data. Other embodiments are described and claimed.
摘要:
Methods and apparatus to provide secure firmware storage and service access are disclosed. One example method may include receiving a request to execute an instruction in a pre-boot environment, determining an identity of the instruction, determining if an access control list includes an entry corresponding to the instruction, and selectively allowing the execution of the instruction if the access control list includes an entry corresponding to the instruction.
摘要:
A temporary memory of a computer system is configured during a boot mode. Page tables are generated for the temporary memory. System memory of the computer system is initialized. Contents of the temporary memory are migrated to the system memory.
