The problem was,

these diagnostic codes were never really documented all that well. The codes that I am presenting here are from documents I have read through, found on the web, found in

old books, documents and technical papers. As a computer technician, I rely on documentation to guide me through these types of messages. Therefore, I hope to provide this to all those other technicians out there who get the opportunity to work on one of these. And, yes, people still use them and some refuse to give them up. The method ibm bios beep codes for reading these codes is pretty straight forward. The first part of the error code indicates the device that is causing the trouble. The second part gives the meaning of the error. You can think of the first part as the test code and the second part as the fault code. A fault code of 00 indicates that no problem was found. Thus 200 means the system memory was tested. The 00 means that no fault was found. 201 would mean a memory error. 202 would mean memory address error; lines 00-15. This page is rather extensive and will be updated on a regular basis. Like all the other codes out there. If you know of any error codes that I am displaying incorrectly or that aren't here. Let me know and I'll get it corrected as soon as I can. Thanks to Mike Rose for erors 129 and 229!

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 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 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 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. For more about beeps and error codes, see ComputerHope.com's Computer POST and beep codes. 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 seated or defective CPU Back to top AMI (Ame
