Beep Codes

Code	Cause	Corrective Action
1-1-2	CPU register test failure	Replace microprocessor 1. If the problem persists, replace microprocessor 2.
1-1-3	CMOS write/read failure	replace the system board.
1-1-4	BIOS checksum failure	Reflash the BIOS firmware. If the problem persists, replace the system board.
1-2-1	Programmable interval-timer failure	Replace the system board.
1-2-2 1-2-3 1-3-1	DMA initialization failure DMA page register write/read failure Main-memory refresh verification failure	Remove and reseat the memory modules. If the problem persists, replace one or more memory modules. If the problem still persists, replace the system board.
1-3-2	No memory installed	Remove and reseat the memory modules. If the problem persists, replace the memory modules. If the problem still persists, replace the system board.
1-3-3 1-3-4 1-4-1 1-4-2 2-1-1 through 2-4-4	Chip set or data line failure in the first 64 KB of main memory Odd/even logic failure in the first 64 KB of main memory Address line failure in the first 64 KB of main memory Parity failure in the first 64 KB of main memory Bit failure in the first 64 KB of main memory	Remove and reseat the memory modules. If the problem persists, replace the memory modules. If the problem still persists, replace the system board.
3-1-1 3-1-2 3-1-3 3-1-4	Slave DMA-register failure Master DMA-register failure Master interrupt-mask register failure Slave interrupt-mask register failure	Replace the system board.
3-2-4	Keyboard-controller test failure	Check the keyboard cable and connector for proper connection. If the problem persists, replace the keyboard. If the problem persists, replace the system board.
3-3-1	CMOS failure	Replace the system board.
3-3-2	System configuration check failure	Replace the system board.
3-3-3	Keyboard controller not detected	Replace the system board.
3-3-4 3-4-2 3-4-3	Screen initialization failure Screen-retrace test failure Search for video ROM failure	Replace the system board.
4-2-1 4-2-2	No timer tick Shutdown failure	Replace the system board.
4-2-3	Gate A20 failure	Replace the system board.
4-2-4	Unexpected interrupt in protected mode	Ensure that all expansion cards are properly seated, and then reboot the system.
4-3-1	Improperly seated or faulty memory modules	Remove and reseat the memory modules. If the problem persists, replace the memory modules. If the problem still persists, replace the system board.
4-3-3	Defective system board	Replace the system board.
4-3-4	Time-of-day clock stopped	Replace the battery. If the problem persists, replace the system board.
4-4-1	Super I/O chip failure (defective system board)	Replace the system board.
4-4-4	Cache test failure (defective microprocessor)	Remove and reseat the specified microprocessor. If the problem still persists, replace the microprocessor.
