RC440BX VC820 For their PS/2 systems, IBM used a system of diagnostic codes to post error codes diagnose trouble spots in a given computer. The problem was, these diagnostic codes were never really documented all that well. asus beep codes 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 for reading these codes is pretty straight forward. The first part of the error code indicates the device that is causing
Hp Beep Codes
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.

by introducing more precise citations. (October 2010) (Learn how and when to remove this template message) The first stage of a typical POST operation. (AMI BIOS) The second stage of a POST. Sometimes, it is shown 'Boot from CD'. https://en.wikipedia.org/wiki/Power-on_self-test (AMI BIOS) A power-on self-test (POST) is a process performed by firmware or software routines immediately after a computer or 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 have self-test routines which are automatically invoked at power-on. The results of tests run by the POST may be displayed on a beep codes 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 process may also set the initial state of the device from firmware. In error code for 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.

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 du
