	Power-on self-test - Wikipedia, the free encyclopedia
		Power On Self Test Beep Codes for AMI and Phoenix BIOS - from PC Hell.
		Power-on self-test (POST) is the common term for a computer's pre-boot sequence.
		If, however, the system supports power savings or quick boot methods, the BIOS may be able to circumvent the standard POST device discovery, and simply program the devices from a preloaded system device table.

		Functionally, the diagnostic tests that are available to user via UI task shall be the same tests that are performed during the Power on Self Test but user shall not necessarily be allowed to run all test.
		Power XLogic has expertise on diagnostic we are offering our services to jointly develop the requirements, architecture and high-level design of Power On Self test (POST) and diagnostics for the Hardware platform in the customer’s systems.
		Unlike the Power on Self Test, which is run automatically at boot time, the diagnostic tests are executed interactively and shall be part of the operational code.

	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.

	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 testing shows the total amount of memory that is installed and functioning correctly.
		After one or two memory boards have been installed and power to the system is turned on, the SPARCstation 2 system will test the functionality of all installed memory (single inline memory modules (SIMMs), and any memory boards).
		See the following SPARCstation 2 installation guides for additional information about diagnostic tests and memory mapping:

	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.

		Assuming you have the motherboard installed into the case, then to do this, simply plug the ATX power connector into the motherboard and then plug in the power for the PC and power it up.
		Many system builders prefer to power up the board before any thing further is installed - this is to verify that the board is in fact good and will power up without problems.
		Generally speaking, if the board powers up and goes through the beep code process, all is well.

	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.

		When an IBM compatible computer is first turned on, the hardware runs a Power-On Self Test (POST).
		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.
		Any combo of beeps after two means that some of your memory is bad, and unless you want to get real technical, you should probably have the guys in the lab coats test the memory for you.
