by firmware or software routines immediately after a computer or other digital electronic device is powered on. This article mainly deals three long beeps during the post sequence on an intel bios are an indication of what type of issue? 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 http://www.computerhope.com/beep.htm 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 show error codes as a sequence of flashes or beeps. In addition to running tests, the POST https://en.wikipedia.org/wiki/Power-on_self-test 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.

consisting only of the Status-Line and optional headers, and is terminated by an empty line. There are no required headers for this class of status code. Since HTTP/1.0 did http://www.restapitutorial.com/httpstatuscodes.html not define any 1xx status codes, servers MUST NOT send a 1xx response to an HTTP/1.0 client except under experimental conditions. A client MUST be prepared to accept one or more 1xx status responses prior http://www.urtech.ca/2016/05/solved-bios-beep-codes-and-error-number-codes-list/ to a regular response, even if the client does not expect a 100 (Continue) status message. Unexpected 1xx status responses MAY be ignored by a user agent. Proxies MUST forward 1xx responses, unless the beep codes connection between the proxy and its client has been closed, or unless the proxy itself requested the generation of the 1xx response. (For example, if a proxy adds a "Expect: 100-continue" field when it forwards a request, then it need not forward the corresponding 100 (Continue) response(s).) Wikipedia Request received, continuing process. This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, post error codes and is terminated by an empty line. Since HTTP/1.0 did not define any 1xx status codes, servers must not send a 1xx response to an HTTP/1.0 client except under experimental conditions. 100 Continue The client SHOULD continue with its request. This interim response is used to inform the client that the initial part of the request has been received and has not yet been rejected by the server. The client SHOULD continue by sending the remainder of the request or, if the request has already been completed, ignore this response. The server MUST send a final response after the request has been completed. See section 8.2.3 for detailed discussion of the use and handling of this status code. Wikipedia This means that the server has received the request headers, and that the client should proceed to send the request body (in the case of a request for which a body needs to be sent; for example, a POST request). If the request body is large, sending it to a server when a request has already been rejected based upon inappropriate headers is inefficient. To have a server check if the request could be accepted based on the request's headers alone, a client must send Expect: 100

Often I hear these codes after a hardware change and then I know that something is not sitting right and I need to remove and reseat it. This is easy to do with RAM, Video Card and Hard Drives. Sometimes a reseat is not the solution and then you need to know what those beeps mean. Each manufacturer may use different codes but the original IBM standard, which is used by many like Pheonix and Award are: BIOS BEEP CODES 1 Short Beep Normal POST - all is good 2 Short Beeps POST Error - error code shown on screen No Beep Power supply or system board problem Continuous Beep Power supply, system board, or keyboard problem Repeating Short Beeps Power supply or system board problem 1 Long, 1 Short Beep System board problem 1 Long, 2 Short Beeps Display adapter problem (MDA, CGA) 1 Long, 3 Short Beeps Enhanced Graphics Adapter (EGA) 3 Long Beeps 3270 keyboard card BIOS ERROR CODES 100 - 199 System Board 200 - 299 Memory 300 - 399 Keyboard 400 - 499 Monochrome Display 500 - 599 Color/Graphics Display 600 - 699 Floppy-disk drive and/or Adapter 700 - 799 Math Coprocessor 900 - 999 Parallel Printer Port 1000 - 1099 Alternate Printer Adapter 1100 - 1299 Asynchronous Communication Device, Adapter, or Port 1300 - 1399 Game Port 1400 - 1499 Color/Graphics Printer 1500 - 1599 Synchronous Communication Device, Adapter, or Port 1700 - 1799 Hard Drive and/or Adapter 1800 - 1899 Expansion Unit (XT) 2000 - 2199 Bisynchronous Communication Adapter 2400 - 2599 EGA system-board Video (MCA) 3000 - 31
