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 technique includes holding a bus interface of a removable device that is inserted into a connector of a computer system in a state to prevent the device from communicating with a communication link. The communication link is coupled to the connector and is associated with operating system access to the device. The method includes a baseboard management controller communicating with the device using a channel other than the communication link while the bus interface of the device is held in the state; the baseboard management controller performing a security operation corresponding to the device based on the communication with the device using the channel; and the baseboard management controller releasing the bus interface of the device from the state to allow the device to communicate with the communication link in response to the baseboard management controller completing the security operation.

Baseboard management controller-based security operations for hot plug capable devices

Example implementations relate to automatic diagnostic mode to identify a potential cause of a boot problem of a system. In an example, the automatic diagnostic mode iteratively isolates subsystems of the system in coordination with a baseboard management controller. For each iteration of subsystem isolation, a system boot is executed while a subsystem is isolated. The system boot is monitored against a watchdog timer of the baseboard management controller to determine if the system boot is successful. If the system boot is successful, the isolated subsystem is marked as a potential cause of the boot problem of the system. If the system boot is unsuccessful, the automatic diagnostic mode continues to iteratively isolate the subsystems.

Automatic diagnostic mode to determine potential cause of boot problem

Examples disclosed herein relate to using a programmable logic device to perform a recovery operation on non-volatile storage devices. In response to receiving an indication to perform recovery, multiple storage devices are set to a predetermined value by the PLD. Recovery of the storage devices is to begin based on the predetermined value setting.

Recovery using programmable logic device

An electronic system includes a fan and a fan controller connected to the fan to control a speed of the fan. The fan controller has storage locations for storing thermal data used by the fan controller to control the speed of the fan. A thermal sensor generates a first portion of the thermal data, which is readable by the fan controller, and which the fan controller stores in a first portion of the storage locations. A device generates a second portion of the thermal data, which is not readable by the fan controller. An agent writes the second portion of the thermal data to a second portion of the storage locations.

Controlling fan speed in electronic system

The disclosed embodiments provide an efficient method and apparatus for avoiding hangs when a computer system is unable to complete a proper boot. Booting is attempted from each device in a standard boot order list until a successful boot occurs. If the standard boot order list is exhausted without a successful boot, the boot sequence is retried after a predetermined time period.
