Details about the main board alarm

When the motherboard is powered on, an alarm is reported, indicating that the problem has been detected. The alarm sound is set by the BIOS on the motherboard. There are two BIOS types: Ami and award. Most motherboards use Award bios. 1) set Award BIOS: Long Sound: the memory stick is not tightly inserted. Short: the system starts normally. Two short: the CMOS settings are incorrect and need to be reset. Long and Short: memory or motherboard error. One long and two short: Incorrect display or video card. One long, three short: Incorrect keyboard controller. One long, nine short: The Flash Ram or EPROM of the motherboard BIOS is incorrect. 2) the BIOS of the AMI is set: Short: Memory refresh failure. Two short: Memory ECC verification error. 3. Short: The system basic memory check fails. Four short: system clock error. 5: CPU error. 6. keyboard controller error. 7. Short: The system real-time mode is incorrect. 8: memory error is displayed. 9. Short: the BIOS chip is incorrect. One long, three short: memory error. One long, eight short: the display data cable or video card is not properly inserted. Phoenix BIOS self-check Bell and Its Significance 1.
