If an error occurs that cannot be reported on the monitor during a boot routine, the system may emit a series of beeps that identify the problem. If an error occurs that cannot be reported on the monitor during a boot routine, the system may emit a series of beeps that identify the problem. NOTE: If the system boots without a keyboard, mouse, or monitor attached, the system will not issue beep codes related to these peripherals. Table of beep codes The table below lists the beep code, the cause, and the corrective actions to take in order to resolve the problem. Code Cause Corrective Action 1-1-2 CPU register test failure Remove and reseat the specified microprocessor. If the problem persists, refer to the Contact Dell Technical Support section below. 1-1-3 CMOS write/read failure Faulty system board. Refer to the Contact Dell Technical Support section below. 1-1-4 BIOS checksum failure This fatal error usually requires that you replace the BIOS firmware. If the system still boots, reflash the System BIOS, otherwise, refer to the Contact Dell Technical Support section below. 1-2-1 Programmable interval-timer failure Faulty system board. Refer to the Contact Dell Technical Support section below. 1-2-2 DMA initialization failure Remove and reseat the memory modules. Refer to the Contact Dell Technical Support section below. 1-2-3 DMA page register write/read failure Remove and reseat the memory modules. Refer to the Contact Dell Technical Support section below. 1-3-1 Main-memory refresh verification failure Remove and reseat the memory modules. If the problem persists, refer to the Contact Dell Technical Support section below. 1-3-2 No memory installed Remove and reseat the memory modules. If the problem persists, refer to the Contact Dell Technical Support section below. 1-3-3 Chip or data line failure in the first 64 KB of main memory Remove and reseat the memory modules. If the problem persists, refer to the Contact Dell Technical Support section below. 1-3-4 Odd/even logic failure in the first 64 KB of main memory Remove and reseat the memory modules. If the problem persists, refer to the Contact Dell Technical Support section below. 1-4-1 Address line failure in the first 64 KB of main memory Remove and reseat the memory modules. If the problem persists, refer to the Contact Dell Technical Support section below. 1-4-2 Parity failure in the first 64 KB of main memory Remove and reseat the memory modules. If the problem persists, refer to the Contact Dell Technical Support section below. 1-4-3 Fail-safe timer test failure Remove and reseat the memory modules. If the problem persists, refer to the Contact Dell Technical Support section below. 1-4-4 Software NMI port test failure Remove and reseat the memory modules. If the problem persists, refer to the Contact Dell Technical Support section below. 2-1-1 through 2-4-4 Bit failure in the first 64 KB of main memory Remove and reseat the memory modules. If the problem persists, refer to the Contact Dell Technical Support section below. 3-1-1 Secondary DMA-register failure Faulty system board. Refer to the Contact Dell Technical Support section below. 3-1-2 Primary DMA-register failure Faulty system board. Refer to the Contact Dell Technical Support section below. 3-1-3 Primary PIC register or interrupt-mask register failure Faulty system board. Refer to the Contact Dell Technical Support section below. 3-1-4 Secondary PIC register or interrupt-mask register failure Faulty system board. Refer to the Contact Dell Technical Support section below. 3-2-2Interrupt vectors initialization or Interrupt vectors loading failure Faulty system board. If the problem persists, refer to the Contact Dell Technical Support section below. 3-2-4 Keyboard-controller test failure Check the keyboard cable and connector for proper connection. Swap keyboard for known good keyboard. If possible, run system diagnostics on the system to determine whether the keyboard or keyboard controller is faulty. If the problem persists, refer to the Contact Dell Technical Support section below. 3-3-1 CMOS failure If possible, Run the system board test in the system diagnostics to isolate the problem. 3-3-2 System configuration check failure Faulty system board. Refer to the Contact Dell Technical Support section below. 3-3-3 Keyboard controller not detected Faulty system board. Refer to the Contact Dell Technical Support section below. 3-3-4 Video memory test failure If possible, run the video test in the system diagnostics. 3-4-1 Video / screen initialization failure If possible, run the video test in the system diagnostics. 3-4-2 Screen-retrace test failure If possible, run the video test in the system diagnostics. 3-4-3 Search for video ROM failure If possible, run the video test in the system diagnostics. 4-2-1 No timer tick Faulty system board. Refer to the Contact Dell Technical Support section below. 4-2-2 Shutdown failure Faulty system board. Refer to the Contact Dell Technical Support section below. 4-2-3 Gate A20 failure Faulty system board. Refer to the Contact Dell Technical Support section below. 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, refer to the Contact Dell Technical Support section below. 4-3-2 No memory modules installed in bank 0 Remove and reseat the memory modules. If the problem persists, refer to the Contact Dell Technical Support section below. 4-3-3 Defective system board Faulty system board. Refer to the Contact Dell Technical Support section below. 4-3-4 Time-of-day clock stopped Reseat the CMOS battery. If the problem persists, refer to the Contact Dell Technical Support section below. 4-4-1 I/O chip set failure Faulty system board. Refer to the Contact Dell Technical Support section below. 4-4-2 BIOS shadowing failure Faulty system board. Refer to the Contact Dell Technical Support section below. 4-4-3 Math coprocessor failure Remove and reseat the specified microprocessor. If the problem persists, refer to the Contact Dell Technical Support section below. 4-4-4 Cache test failure Remove and reseat the specified microprocessor. If the problem persists, refer to the Contact Dell Technical Support section below.
