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.
Channel 9, however, was not a community website and did not host any content made by the community. [1] That had not always been the case. The site once hosted discussion forums, [6] as well as a wiki based on Microsoft's own FlexWiki. The wiki had been used to provide ad hoc feedback to Microsoft teams, such as the Internet Explorer team. [7]
However LPC connectors are not standardized, with between 9 and 19 pins and both 2.54 mm and 2 mm pin headers commonly used. Therefore, an LPC POST card may have to auto-detect first the pin assignment used. Another option are USB POST cards such as AMI Debug Rx, which use the debug port common on USB 2.0 EHCI controllers.

The IBM Personal Computer included ROM-based firmware called the BIOS; one of the functions of that firmware was to perform a power-on self test when the machine was powered up, and then to read software from a boot device and execute it. Firmware compatible with the BIOS on the IBM Personal Computer is used in IBM PC compatible computers.
APM defines five power states for the computer system: Full On: The computer is powered on, and no devices are in a power saving mode. APM Enabled: The computer is powered on, and APM is controlling device power management as needed. APM Standby: Most devices are in their low-power state, the CPU is slowed or stopped, and the system state is saved.

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 ...
