| | Computer Post / Beep codes |
| | The computer POST (Power On Self Test) tests the computer, insuring that it meets the necessary system requirements before booting up. | | | The first step of POST is the testing of the Power Supply to ensure that it is turned on and that it releases its reset signal. | | | An irregular POST is a beep code which is different from the standard, which can be either no beeps at all or a combination of different beeps indicating what is causing the computer not to past the POST. |

| | Power On Self Test - Adrian's Rojak Pot Forums |
| | If this test fails, the only tools the BIOS has to work with are the registers in the CPU, the system timer (hopefully) and the case speaker. | | | Upon receiving Power Good from the Power Supply, or releasing the Reset button, the CPU starts cycling and makes a hardwired jump to address FFFF0 (hex) and fetches and executes the first instruction there. | | | This is not the normal memory test, this is just to see if the CPU can read and write to low addresses in main memory. |

| | PC Hell: BIOS Error Beep Codes |
| | When an IBM compatible computer is first turned on, the hardware runs a Power-On Self Test (POST). | | | One of the chips on your motherboard is broken. | | | If errors are encountered during this POST test, they are usually displayed via an audio beep or in the form of a code number flashed across the screen. |

| | BIOS Power-On Self Test (POST) |
| | You may have encountered a PC that, when the power was turned on, made beeping sounds and then stopped without booting up. | | | As the startup process continues, it performs additional tests, such as the memory test that some machines show on the screen. | | | The POST process is performed very quickly on most newer computers, and (based upon the equipment manufacturer) you may not even notice that it is happening, unless of course a problem occurs. |

| | Quick Power On Self Test / Quick Boot |
| | Enabling this setting will cause the BIOS power-on self test routine to skip some of its tests during bootup. | | | Fortunately (or unfortunately) the POST memory test is virtually useless to detect transient memory errors (as opposed to hard errors that you would discover the first time you powered up the machine with the new memory in it), so once your system is running and stable, you can in most cases enable this setting safely. | | | One of the key things this setting usually does when enabled is cause the POST to skip checking all of extended memory for errors. |
