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").
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.
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).

UEFI replaces the BIOS that was present in the boot ROM of all personal computers that are IBM PC compatible, [5] [6] although it can provide backwards compatibility with the BIOS using CSM booting. Unlike its predecessor, BIOS, which is a de facto standard originally created by IBM as proprietary software, UEFI is an open standard maintained ...
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 ...
The Kernel-Mode Driver Framework (KMDF) model continues to allow development of kernel-mode device drivers but attempts to provide standard implementations of functions that are known to cause problems, including cancellation of I/O operations, power management, and plug-and-play device support. Apple has an open-source framework for developing ...
Phoenix Technologies Ltd. is an American company that designs, develops and supports core system software for personal computers and other computing devices. The company's products – commonly referred to as BIOS (Basic Input/Output System) or firmware – support and enable the compatibility, connectivity, security and management of the various components and technologies used in such devices.
On a desktop computer the port is simply a connector, usually mounted on a bracket at the back accessible from outside the machine, connected to motherboard sources of SATA, USB, and power at 5 V and 12 V. No change is required to drivers, registry or BIOS settings and the USB support is independent of the SATA connection. [citation needed]
