What is POST-(Power On Self Test)...?
Power On Self Test is a test sequence initiated and controlled by the system BIOS each time power is applied to the computer. The POST sequence starts when the computer is turned on and continues to the point when the system is booted(i.e., when the operating system is loaded). The purpose of the POST routine is to check all of the major functions and subsystems of the computer (such as the memory, keyboard, video, hard and floppy drives, etc.) to make sure everything is functioning properly before an attempt is made to load the operating system and other programs which the computer may need to run.

What are POST Error Codes?
POST codes are output by the system BIOS during the Power On Self Test sequence. POST codes are typically output as hexadecimal numbers. These numbers (or codes) identify each of the various components and functions ( a circuit or group of circuits) that are tested after the system is powered up. How do I see the generated POST Error Codes?
POST codes can be seen as they are being generated by your BIOS with any of Ultra-X's QuickPOST Series P.O.S.T. Card. Simply plug any of the QuickPOST Series cards into your PC's PCI or ISA slot or MicroPOST into your parallel port and watch as the BIOS as the BIOS performs its tests. The QuickPOST Series cards as well as the MicroPOST parallel adapter display HEX digits which consist of alphanumeric characters 0-9 & the letters A-F.
