Codes AMI BIOS Post Procedures - For BIOS's of Feb 1991: NMI Disable NMI interrupt line to the CPU is disabled by setting bit 7 I?O port 70h (CMOS) Power On Delay Once the keyboard controller gets power, it sets the hard and soft reset bits. Check the keyboard controller or clock generator if a failure occurs Initialize Chipsets ami bios beep codes continuous Check the BIOS, CLOCK and chipsets Reset Determination The BIOS reads the bits in the keyboard controller to see if a hard or soft reset is required (a soft reset will not test memory above 64K). Failure could be the BIOS or keyboard controller ROM BIOS Checksum The BIOS performs a checksum on itself and adds a preset factory value that should make it equal to 00. If a failure occurs, check the BIOS chips Keyboard Test A command is sent to the 8042 keyboard controller which performs a test and sets a buffer space for commands. After the buffer is defined the BIOS sends a command byte, writes data to the buffer, checks the high order bits of the internal keyboard controller and issues a No Operation (NOP) command CMOS Shutdown byte in CMOS RAM offset 0F is tested, the BIOS checksum calculated and diagnostic byte 0E updated before the CMOS RAM area is initialized and updated for date and time. Check the RTC and CMOS chip or battery if a failure occurs

Two beeps: Parity Circuit FailureProblem: Motherboard problem or failed RAM.Solution: Troubleshoot the motherboard and/or the RAM. Three beeps: Base 64K RAM failureProblem: There is a failure within the first 64K of memory.Solution: Troubleshoot the motherboard and/or the RAM. Four beeps: System Timer FailureProblem: One or more of the system timers on the motherboard has failed; usually indicates motherboard failure.Solution: Troubleshoot the motherboard. You may need to replace it. Five beeps: Processor FailureProblem: The processor is generating an error condition. This does not mean that the processor is not working--with a dead processor, the computer won't boot at all.Solution: Check if the processor is overheating, and whether it is set correctly on the motherboard. Troubleshoot the motherboard. Six beeps: Keyboard controller or gate A20 failureProblem: Keyboard, keyboard controller or motherboard error.Solution: Check if the keyboard is connected properly. Use another keyboard to see if the problem persists. If it does, look for the keyboard controller chip on the motherboard and see if it is seated properly and that it is not damaged. If the problem co
is first switched on or reset, it performs a special diagnostic test called a POST (Power-On Self Test). To check all of the components in the PC, the POST program sends out a signal to each device initialising each device's built-in self-test procedure. advertisement The POST test is a two stage process, first it will check all of the basic components including amongst other things, the system clock, the processor, RAM, the keyboard controller and the video card. When a device fails the first part of the POST the BIOS will send a series of beeps from the PC's speaker (internal) to inform the PC user that there is a problem. These beeps are coded allowing the user to diagnose the troublesome component. After the video has been tested successfully the BIOS will then display any errors encountered on the screen. The error message will be either a numeric code or a text message. When the POST has been completed successfully the PC will make a short beep to let the user know everything is as it should be. Below are some common beep codes for AMI and Phoenix BIOS. AMI BIOS error beep codes 1 Beep - Memory Refresh Failure (check memory) 2 Beeps - Memory Parity Error in first 64KB block (check memory) 3 Beeps - Memory Read/Write Error in first 64KB block (check memory) 4 Beeps - Motherboard timer not functioning (possible motherboard replacement) 5 Beeps - Processor Error (may need replacement Processor) 6 Beeps - Gate A20/keyboard controller failure (possible motherboard replacement) 7 Beeps - Processor Exception Interrupt Error (may need replacement Processor) 8 Beeps - Display Memory Read/Write Failure (reseat or replace video card) 9 Beeps - ROM checksum Error (replace BIOS chip or motherboard) 10 Beeps - CMOS shutdown Read/Write error (possible motherboard replacement) 11 Beeps - Bad Cache Memory - test failed (replace cache memory) Phoenix BIOS error beep codes Phoenix BIOS beep codes are a series of beeps separated by a pause, for example: beep --- beep beep --- beep --- beep beep would be 1-2-1-2 1-1-4-1 - Cache Error (level 2) 1-2-2-3 - BIOS ROM Checksum 1-3-1-1 - DRAM Refresh Test 1-3-1-3 - Keyboard controller test 1-3-4-1 - RAM Failure on address line xxxx (check memory) 1-3-4-3 - RAM Failure on data bits xxxx of low byte of memory bus 1-4-1-1 - RAM Failure on data bits xxxx of high byte of memory bus 2-1-2-3 - ROM copyright no
