Ketika sebuah komputer dinyalakan pertama
kali, atau reboot, BIOS melakukan power-on self test (POST) untuk melakukan tes
hardware, memastikan bahwa seluruh sistem bekerja sebagaimana mestinya. Pada
kondisi normal, POST akan menampilkan pesan error. akan tetapi bila BIOS
mendeteksi error sebelum mengakses video card, atau ada masalah dengan video
card, BIOS akan menghasilkan sejumlah suara Beep, dan pola beep yang dihasilkan
menandakan jenis masalah yang dideteksi oleh oleh BIOS. Karena ada berbagai
merek BIOS, tidak ada standard Kode Beep untuk setiap BIOS.
Berikut daftar kode beep untuk AMI System
dan Phoenix System.
AMI Beep Codes
Beep Code Meaning
1 beep DRAM refresh failure. There is a
problem in the system memory or the motherboard.
2 beeps Memory parity error. The parity
circuit is not working properly.
3 beeps Base 64K RAM failure. There is a
problem with the first 64K of system memory.
4 beeps System timer not operational. There
is problem with the timer(s) that control functions on the motherboard.
5 beeps Processor failure. The system CPU
has failed.
6 beeps Gate A20/keyboard controller
failure. The keyboard IC controller has failed, preventing gate A20 from
switching the processor to protect mode.
7 beeps Virtual mode exception error.
8 beeps Video memory error. The BIOS cannot
write to the frame buffer memory on the video card.
9 beeps ROM checksum error. The BIOS ROM
chip on the motherboard is likely faulty.
10 beeps CMOS checksum error. Something on
the motherboard is causing an error when trying to interact with the CMOS.
11 beeps Bad cache memory. An error in the
level 2 cache memory.
1 long beep, 2 short Failure in the video
system.
1 long beep, 3 short A failure has been
detected in memory above 64K.
1 long beep, 8 short Display test failure.
Continuous beeping A problem with the
memory or video.
BIOS Beep Codes
nomer menandakan pause (sela) antar urutan
beep. Contoh: 1-2-3 menandakan satu beep diikuti sela diikuti dua beep diikuti
sela dan diikuti tiga beep. Phoenix
