This article mainly deals with personal computers, but many other embedded systems

such as those in major appliances, avionics, communications, or medical equipment also have self-test routines which are automatically invoked at power-on. The results of tests run by the POST may be displayed on a panel that is http://www.computerhope.com/beep.htm part of the device, output to an external device, or stored for future retrieval by a diagnostic tool. Since a self-test might detect that the system's usual human-readable display is non-functional, an indicator lamp or a speaker may be provided to show error codes as a sequence of flashes or beeps. In addition to running tests, the POST process may also set the initial state of the device from firmware. In the case of https://en.wikipedia.org/wiki/Power-on_self-test a computer, the POST routines are part of a device's pre-boot sequence and only once they complete successfully is the bootstrap loader code invoked to load an operating system.

These other duty-specific programs are generally known collectively as option ROMs or individually as the video BIOS, SCSI BIOS, etc. The principal duties of the main BIOS during POST are as follows: verify CPU registe
