A method for configuring a computer system memory, includes powering on the computer system; retrieving options for initializing the computer system; assigning to a first segment of the memory a first pre-defined setting; assigning to a second segment of the memory a second pre-defined setting; and booting the computer system.

Configurable computer memory

A system for securely and reliably transferring startup script files over a network may include a unified extensible firmware interface (UEFI) network stack on a client server wherein the client server requests startup script over the network upon startup of the client server using a secure transfer network protocol and receives over the network the startup script. A computing device may comprise a unified extensible firmware interface (UEFI) shell to request a download of startup script, over a network, upon startup of the client server wherein the startup script is staged in a provisioned storage device within the client server to be mounted as local file systems in the client server. The UEFI shell.

Securely and reliably transferring startup script

A technique includes, in a first phase of a secure boot of a computer system, executing boot code of the computer system to access a first version of a secure boot key database to authenticate driver code. The first version of the secure boot key database stores a key corresponding to a plurality of drivers. The technique includes executing the boot code to automatically prepare the secure boot key database for a second phase of the secure boot in which operating system bootloader code is executed. Preparing for the second phase includes executing the boot code to automatically replace the first version of the secure boot key database with a second version of the secure boot key database, and the second version of the secure boot key database stores a key, which corresponds to the operating system bootloader code. The technique includes in the second phase of the secure boot, executing the boot code to access the secure boot key database to authenticate the operating system bootloader code.

Automatically replacing versions of a key database for secure boots

An example computing system in accordance with an aspect of the present disclosure includes a first controller and a second controller. The first controller is to verify integrity of a first root of trust (ROT), and generate an integrity signal indicating the results. The second controller is to verify integrity of a second ROT, write the firmware image to the first controller, and verify integrity of the written firmware image.

Multiple roots of trust to verify integrity

Example implementations relate to a self-tune controller. For example, the self-tune controller may poll, via an out-of-band data stream, low-level operation information about a processor or a bus of a computing system under a present workload. At least some of the low-level operation information may be descriptive of a nature of traffic on the bus. The self-tune controller may program, via an out-of-band control signal, a setting of the computing system for the present workload based on the low-level operation information.

Self-tune controller

In one example in accordance with the present disclosure, a method for determining operating frequencies includes receiving a warranty period for a computer component. The method includes determining an operating frequency that will cause a predicted life cycle of the computer component operating at the operating frequency to fall within the warranty period. The method includes setting the computer component to operate at the operating frequency.

Operating frequency determination based on a warranty period

Using a cryptographic co-processor in a computing system to encode data parameters determined during initialization, or during operation, or determined from machine specific values or states to bind data optionally to a specific machine, a specific cryptographic co-processor, or a specific operating environment machine state.

Binding data to computers using cryptographic co-processor and machine-specific and platform-specific keys

In at least some embodiments, a computer system includes a processor and a firmware storage medium in communication with the processor. The firmware storage medium stores a default image invoked during a boot process and selectively stores a customized image. If the customized image is stored by the firmware storage medium, the boot process selectively substitutes at least part of the default image with at least part of the customized image.

Firmware storage medium with customized image

A method and apparatus for host enumeration process. One embodiment of the method provides a bit to indicate to the host whether enumeration process should start or continue. The bit may be set when the shared resource process has been successfully completed, or the bit may be set if too much time has elapsed since the shared resource process has started, or the bit may be set if too much time has elapsed before the shared resource process is started, or the bit may be set if the shared resource process has not been performed successfully, or the bit may be set if the port is open and it is unnecessary to perform the shared resource process.

Method and apparatus for performing a host enumeration process

Example methods, apparatus and articles of manufacture to diagnose temperature-induced memory errors are disclosed. A disclosed example method to diagnose a temperature-induced memory error includes detecting a memory error associated with a memory device, and writing a highest measured temperature of the memory device in the memory device when the memory error is detected, the highest temperature measured temporally near the detected memory error.

Methods, apparatus and articles of manufacture to diagnose temperature-induced memory errors

In at least some embodiments, a system comprises a plurality of electrical devices and management logic coupled to the electrical devices. While the electrical devices are each in a pre-boot environment, the management logic obtains information from the electrical devices and uses the information to determine electrical compatibility of, and/or configure, the electrical devices.

Controller receiving a configuration command while receiving an auxiliary supply voltage

A method and system manages revisions of software code for one or more servers in an infrastructure. An indication of the version of the code currently residing with one of the servers is transmitted to the infrastructure. An indication of the version of the code currently residing with the infrastructure for the server's type is also transmitted to the one of the servers. A determination is made as to whether the server's version should be updated to the infrastructure's, whether the infrastructure's version should be updated to the server's, or neither based on the transmitted indications in view of a set of preconfigured update rules. If the infrastructure's version should be updated to the server's, the image of the code currently residing with the infrastructure is replaced with an image of the code currently residing with the server. If the server's version should be updated to the infrastructure's, the image of the code currently residing with the server is replaced with an image of the code currently residing with the infrastructure for the server's type.
