stage of a POST. Sometimes, it is shown 'Boot from CD'. (AMI BIOS) msi beep codes A power-on self-test (POST) is a process performed by firmware or software routines immediately after a computer or asrock beep codes other digital 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 http://www.bioscentral.com/beepcodes/ibmbeep.htm 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 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 https://en.wikipedia.org/wiki/Power-on_self-test 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 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.

beeps and fails to boot, what do the beeps mean? On startup, computers perform a Power-on Self Test, commonly referred to as a POST. If problems are found while https://kb.iu.edu/d/afzy booting, you can usually diagnose them using the error codes displayed on the screen. However, if nothing displays on the screen, the computer might use sounds (i.e., beep codes) to tell you what is wrong. Many of these errors indicate hardware problems that a service technician should fix. However, some errors are easily fixed. For example, keyboard controller errors often mean that your keyboard isn't plugged beep codes in. Following are beep codes for some common brands of BIOS for PCs. For information about Mac beep codes or startup tones, see Apple Support's About Mac computer startup tones. Note: Many BIOSes will have different beep codes even if they appear to be from the same manufacturer. This is because motherboard manufacturers reprogram codes to reflect their own customizations. You can often go to the ibm pc error website for the motherboard's manufacturer to find the updated codes, but you may find cases where the manufacturer simply does not document the changes.

On this page: AwardAMI (American Megatrends)AST BIOSCompaqPhoenixIBM DesktopIBM ThinkPadMylexQuadtel BIOS Award Award BIOSes typically use more screen errors than beep codes. For Award BIOSes manufactured by Phoenix Technologies, note the following from the Phoenix Technologies AwardBIOS Error Messages page: "The only AwardBIOS beep code indicates that a video error has occurred and the BIOS cannot initialize the video screen to display any additional information. This beep code consists of a single long beep followed by two short beeps. Any other beeps are probably RAM (Random Access Memory) problems." Award BIOSes not manufactured under Phoenix Technologies use the following beeps; this information is from the BIOS Central Award BIOS Beep Codes page: Beeps Meaning 1 long, 2 short Video adapter error: Bad or improperly seated video card Repeating beeps Memory error: Bad or improperly seated RAM 1 long, 3 short Bad video RAM or video card not present High-frequency beeps Overheated CPU: Check fans Repeating high/low beeps CPU: Improperly s
