Abstract: Mechanisms are provided, in a bare metal computing device, for executing a network based boot operation for booting the bare metal computing device. In response to powering-on the bare metal computing device, firmware is executed that executes a stub from a virtual media image accessible by the bare metal computing device. The configuration information of the bare metal computing device indicates that the bare metal computing device is being booted from a local media. The stub configures the firmware environment and a network boot program to utilize a network connection by modifying the configuration information of the bare metal computing device to indicate that the bare metal computing device is being booted from a network device. A control program is obtained from a remotely located boot server using the network boot program and is executed to complete the booting of the bare metal computing device.

Abstract: A mechanism is provided for improved firmware storage and maintenance. For each master device in a plurality of master devices: an amount of flash memory space required by the master device is identified and the amount of Flash memory space from a Flash component is allocated to the master device as a virtual Flash memory allocation. An initial sector location of the virtual Flash memory allocation in a data structure is recorded as an offset into the Flash component and a length of the virtual Flash memory allocation and device information is also recorded in the data structure. Data that allows the master device to boot up is then loaded into the virtual Flash memory allocation.

Abstract: Mechanisms for executing a bare metal boot operation for bare metal booting a control program are provided. These mechanisms boot a computing device to a hypervisor ownership phase of the bare metal boot operation. During the hypervisor ownership phase of the bare metal boot operation a hypervisor is loaded and controls and manages platform hardware of the computing device. The computing device is then booted from the hypervisor ownership phase to a transition phase in which the hypervisor releases control and management of the platform hardware of the computing device to the control program. The computing device is then booted from the transition phase to a control program ownership phase in which the control program is in full control and manages the platform hardware. The bare metal boot operation is performed without restarting the computing device and without cycling through initialization of firmware.

Abstract: Configuring expansion component interconnect (‘ECI’) physical functions on an ECI device in a computing system, including: configuring by an ECI device configuration manager, during run-time of the computing system, vital product data to include an ECI physical function configuration, wherein the ECI physical function configuration comprises data describing a type of ECI physical function; retrieving by an ECI device configuration manager, upon a subsequent startup of the computing system, the ECI physical function configuration from the vital product data; and configuring, by an ECI device configuration manager, a physical function of the ECI device to carry out the type of ECI physical function described in the ECI physical function configuration.

Abstract: A method identifies a plurality of PCI devices in a computer system by an associated PCI device handle, wherein each of the PCI devices is also associated with a default EFI device driver. The method further identifies a target PCI device to be disabled from within the plurality of PCI devices, provides a dummy driver that enables fewer functions for the target PCI device than would the default EFI device driver, and binds the dummy driver to the target PCI device instead of binding the default EFI device driver associated with the target PCI device. The dummy driver may be used to effectively disable the target PCI device so that the POST does not hang up or completes faster without loading the default EFI device driver.

Abstract: A maximum power usage setting for a computing device is based on one or more of: a user-specified setting corresponding to how often a frequency of a processor of the computing device is likely to have to be decreased to reduce power usage by the computing device; an average frequency of the processor during a previous period in which the computing device was operated; a minimum frequency of the processor during the previous period; a maximum power that the computing device used during the previous period; and, a nominal frequency of the processor. When the computing device starts to use more power than the maximum power usage setting, the power used by the computing device is reduced so as not to exceed the setting, such as by decreasing the frequency at which the processor operates.

Abstract: A method and apparatus for extending initialization of a personal data processing system using multiple levels of bootstrap code is provided. The first level of bootstrap code is stored in a non-volatile memory device associated with a processor of the data processing system. The second level of code is stored on a system partition or other section of a fixed disk memory storage device.

A first initialization procedure is performed by executing the first level of bootstrap code, where the first initialization procedure performs a memory check self-test of the data processing system and conditions the data processing system for a program load. The second level of bootstrap code is then executed performing a second initialization procedure which performs specific initialization steps according to the configuration of the second level of bootstrap code.
