For example, if the keyboard is not detected, a particular pattern of beeps will inform you of that fact. The patterns of beeps contain messages about the nature of the problem detected. If the hardware is not detected or is found not to be operating properly, the BIOS issues an error message which may be text on the display screen and/or a series of coded beeps, depending on the nature of the problem.The pattern of beeps may be a variable numbers of short beeps or a mixture of long and short beeps, depending on what type of BIOS is installed. If the necessary hardware is detected and found to be operating properly, the computer begins to boot. Random access memory, disk drives, and other hardware are working correctly. When power is turned on, POST (Power-On Self-Test) is the diagnostic testing sequence that a computer's basic input/output system (or "starting program") runs to determine if the computer keyboard,
