Typical POST screen (AMI BIOS) Typical UEFI-compliant BIOS POST screen (Phoenix Technologies BIOS) Summary screen after POST and before booting an operating system (AMI BIOS) A power-on self-test ( POST ) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on.
As of 2021 the supplied printer-drivers support a total of 3,088 HP printer models; [3] many of these for low-end models are free and open-source (FOSS), licensed under MIT, BSD, and GPL licenses, but others (including all color laser MFC printers on the market for years) require proprietary binary blobs ("plug-ins").
In computing, BIOS (/ ˈ b aɪ ɒ s,-oʊ s /, BY-oss, -ohss; Basic Input/Output System, also known as the System BIOS, ROM BIOS, BIOS ROM or PC BIOS) is a type of firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup).

coreboot, formerly known as LinuxBIOS, [5] is a software project aimed at replacing proprietary firmware (BIOS or UEFI) found in most computers with a lightweight firmware designed to perform only the minimum number of tasks necessary to load and run a modern 32-bit or 64-bit operating system.
The HP MPA utility pre-configures some driver default settings in a managed HP UPD environment. Settings made within the HP MPA utility control the HP UPD at a user level. The resulting policies are maintained for every printer attached to the HP UPD. They are global user policies that affect HP UPD users. HP UPD Active Directory Templates
For backward compatibility, some UEFI implementations also support booting from MBR-partitioned disks through the Compatibility Support Module (CSM) that provides legacy BIOS compatibility. [50] In that case, booting Linux on UEFI systems is the same as on legacy BIOS-based systems.
BIOS interrupt calls perform hardware control or I/O functions requested by a program, return system information to the program, or do both. A key element of the purpose of BIOS calls is abstraction - the BIOS calls perform generally defined functions, and the specific details of how those functions are executed on the particular hardware of the system are encapsulated in the BIOS and hidden ...
Unlike Mac clones that contain little or no original Apple hardware, a Mac conversion is an aftermarket enclosure kit that requires the core components of a previously purchased, genuine Apple Mac computer, such as the Macintosh ROM or the motherboard, in order to become a functional computer system.
