Abstract: Examples for booting a processor are described herein. In an example, a pure hardware parameter associated with a processor, from amongst a plurality of processors, is determined to identify the processor. A firmware appropriate for booting of the processor is identified, based on the identified processor. Then, a Serial Peripheral Interface Read-Only Memory (SPI-ROM) is selected for loading the identified firmware to boot the identified processor. As part of selecting the firmware, the identified firmware is loaded to the SPI-ROM.

Abstract: Example implementations relate to Basic Input Output System updates. In some examples, a computing device can include a memory, a processor to, in response to completion of a Basic Input/Output System (BIOS) update, generate and store a boot status variable in the memory, determine whether the BIOS update was successful, in response to the BIOS update being successful, delete the boot status variable from the memory and perform a power event, and in response to the BIOS update being unsuccessful, perform a BIOS recovery.

Abstract: In example implementations, an apparatus is provided. The apparatus includes an interface, an integrated graphical processing unit (GPU), a discrete GPU, and a controller. The interface is to receive a connection to an external display device. The integrated GPU and the discrete GPU are communicatively coupled to the interface. The controller is communicatively coupled to the integrated GPU and the discrete GPU and is to deactivate the discrete GPU and activate the integrated GPU in response to detection of the external display device connected to the interface.

Abstract: Examples for generating a common video signal for an integrated GPU and the graphical processing device, based on a common display mode setting, are described. In an example, a common display mode setting is determined based on a first set of display mode settings supported by the integrated GPU and a second set of display mode settings supported by the graphical processing device. Based on the common display mode setting, video signals for the integrated GPU and the graphical processing device are generated.

Abstract: Examples of of centralized access control of an input-output (I/O) resource of a computing device are described herein. In an example, access rights available for a user for the I/O resource are determined based on user identification data, and access to the I/O resource to the user is controlled centrally based on the available access rights associated with the user.

Abstract: In an example implementation according to aspects of the present disclosure, a system comprising a memory and a controller coupled to the memory. The controller receives a transitionary firmware package. The controller extracts a transitionary firmware from the transitionary firmware package. The controller writes the transitionary firmware to memory, wherein the transitionary firmware comprises a reduced functionality for each of a set of central processing units. The controller identifies the CPU currently installed in the system and determines a full featured firmware corresponding to that CPU. The controller writes the full featured firmware to the memory.

Abstract: The present subject matter relates to techniques for storing POST codes in electronic tags. In an example, a POST code corresponding to each test of a Power ON Self-Test (POST) process may be stored in a Complementary Metal-Oxide Semiconductor (CMOS) chip of a motherboard. The POST code may be indicative of a status of a respective test of the POST process. The POST code corresponding to each test of the POST process is simultaneously stored in a memory of an electronic tag. The electronic tag may be communicatively coupled to the motherboard and the CMOS chip. The POST codes are retrievable from the memory of the electronic tag by an end user of the computing device when the motherboard is powered OFF.
