electronic device is powered on. 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 http://www.computerhope.com/beep.htm which are automatically invoked at power-on. The results of tests run by the POST may be displayed on a panel that is 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 https://en.wikipedia.org/wiki/Power-on_self-test 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 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.

The beep code is followed by a user-visible code displayed on the Diagnostic LEDs. Note Common supported codes are post error beeps listed in these tables. For more platform-specific beep codes, and POST Progress codes, see the Technical Product Specification for your product. Beeps Error Message Description 1 short USB device action Short beep sounded whenever USB device is discovered in POST, or inserted or removed during runtime. 1 long Intel Trusted Execution Technology (Intel TXT) security violation System halted because Intel Trusted Execution Technology detected a potential violation of system security. 3 short Memory error System halted because a fatal error related to the memory was detected. 3 long and 1 short1 CPU mismatch error System halted because a fatal error related to the CPU family/core/cache mismatch was detected. 2 short Recovery started BIOS Recovery boot has been initiated 4 short Recovery failed BIOS Recovery has failed. This typically happens so quickly after recovery is initiated, that it sounds like a 2-4 beep code. 1 This beep code only applies to the Intel Server Boards and Systems supporting the Intel Xeon Processor E5-2600 v3 product family.The Integrated BMC generates beep codes when it detects failure conditions. Beep codes are sounded each time the problem is discovered, such a
