BIOS Beep Codes

What is a BIOS Beep Code?
When you power on a computer the BIOS immediately takes control of the computer and performs the P.O.S.T (Power On Self Test). At the end of the POST the computer will play an audible 'BEEP' through either the PC's internal speaker of through speakers attached to the sound card (if you have a built-in sound chip). If the POST completed successfully without detecting any problems with then system will play a single short beep to let you know the test is complete and the computer will continue to startup and load the operating system.

If during the POST the BIOS detects a problem it will normally display a visual error message on the monitor explaining what the problem is. However, if a problem is detected before the BIOS initializes the video card, or a video card is not present or not detected then the BIOS will play several 'BEEPS' through the speaker to let you know there is a problem. Depending on the type of the BIOS you have the BIOS may play beeps in a specific pattern to indicate what the problem is, or play the same beep a number of times indicating the problem. It is very important that you pay close attention to the number and/or pattern of the beeps your computer plays on startup.

Below is a table of the most common AMI, Phoenix and Award BIOS beep codes.

AMI (American Megatrends International) BIOS Beep Codes.
AMI BIOS uses beeps of the same length and pitch. The error is displayed as a number of beeps. For example, 4 beeps indicated a timer failure.

BEEP CODE MEANING POSSIBLE CAUSE
1 Beep (No video) Memory refresh failure Bad memory
2 Beeps Memory parity error Bad memory
3 Beeps Base 64K mem failure Bad memory
4 Beeps Timer not operational Bad motherboard
5 Beeps Processor error Bad processor
6 Beeps 8042 Gate A20 failure Bad CPU or Motherboard
7 Beeps Processor exception Bad processor
8 Beeps Video memory error Bad video card or memory
9 Beeps ROM checksum error Bad BIOS
10 Beeps CMOS checksum error Bad motherboard
11 Beeps Cache memory bad Bad CPU or motherboard

Award BIOS Beep Codes
Award BIOS uses beeps of varying duration. A long beep will typically last for 2 seconds while a short beep will last only 1 second. Award BIOS also uses beeps of different frequency to indicate critical errors. If an Award BIOS detects that the CPU is overheating it may play a high pitched repeating beep while the computer is running.

BEEP CODE MEANING POSSIBLE CAUSE
1 Long, 2 Short Video adapter failure Bad video adapter Repeating (Endless loop) Memory error Bad memory or bad connection
1 Long, 3 Short Video adapter failure Bad video adapter or memory High freq. beeps (while running) CPU is overheating CPU fan failure Repeating High, Low beeps CPU failure Bad processor

Phoenix BIOS Beep Codes

Phoenix BIOS uses beep code patterns to indicate problems. In the table below the '-' indicates a brief pause between beeps.

Example: 1 - 1 - 2 would sound like BEEP (pause) BEEP (pause) BEEP BEEP

beep Kode pada BIOS

apa itu beep kode pada BIOS
ketika rekan - rekan menyalakan komputer, BIOS dengan segera mengontrol komputer dan menjalankan P.O.S.T (Power On Self Test). di akhir POST komputer akan mengeluarkan bunyi 'beep' lewat internal speaker dalam PC atau speaker yang menancap pada sound card. jika proses POST selesai tanpa mendeteksi masalah maka system akan mengeluarkan 1 kali bunyi 'beep' yang pendek untuk start up dan membaca sistem operasi

jika dalam proses POST, BIOS mendeteksi masalah, komputer akan memunculkan pesan kesalahan pada layar monitor. tapi jika kesalahan terdeteksi sebelum menginisialisasi video card atau vga tidak terdeteksi, BIOS akan mengeluarkan beberapa bunyi 'beep' lewat speaker untuk memberitahukan user dimana kesalahan terjadi. tergantung pada jenis BIOS yang rekan - rekan miliki, BIOS mungkin mengeluarkan bunyi beep dalam pola tertentu atau bunyi yang sama beberapa kali untuk menunjukan masalah. hal ini sangat penting untuk rekan - rekan untuk memperhatikan jumlah atau pola dari bunyi beep di komputer rekan - rekan

berikut ini adalah beep kode yang sering terjadi pada AMI, Phoenix dan Award BIOS

AMI(American Megatrends International) BIOS kode

AMI BIOS menggunakan bunyi beep yang panjangnya sama. error ditampilkan dalam bentuk nomor beep. 4 beep mengindikasikan 4kali failure.

BEEP KODE DAN KEMUNGKINAN ARTINYA

1 beep : tidak ada video, memory reset failure for bad memory
2 Beeps : memory parity error Bad memory
3 Beeps :Base 64K failure Bad memory
4 Beeps : Timer not opertational bad motherboard
5 Beeps : processor error bad processor
6 Beeps : 8042 Gate A20 failure Bad CPU or motherboard
7 Beeps : Processor exception Bad processor
8 Beeps : Video memory error Bad video card or memory
9 Beeps : ROM checksum error Bad BIOS
10 Beeps : CMOS checksum error Bad motherboard
11 Beeps : Cache memory bad Bad CPU or motherboard

AWARD BIOS Beep kode
AWARD BIOS menggunakan bunyi beep berbagai macam variasi durasi. beep yang panjang kira - kira 2 detik dan beep pendek 1 detik. Award BIOS juga menggunakan bunyi beep dalam berbagai frequensi untuk mengindikasikan error, jika Award BIOS mendeteksi cpu yang overheat maka akan mengeluarkan bunyi beep yang berulang - ulang ketika komputer masih berjalan.
BEEP KODE DAN KEMUNGKINAN ARTINYA
1 Panjang, 2 pendek : Video adapter failure, Bad video adapter, berulang kali: Memory error bad memory atau bad connection.
1 panjang, 3 pendek : video adapter failure, bad video adapter atau memory, beep berfrequensi tinggi(ketika PC digunakan) CPU overheat CPU fan failure, repeating high, low beeps CPU failure, bad processor

Phoenix BIOS Beep kode
Phoenix BIOS menggunakan beep kode untuk mengindikasikan masalah. berikut ini adalah kode beep dari phoenix BIOS '-' menunjukan jeda singkat antara bunyi beep
contoh : 1 - 1 - 2 akan berbunyi seperti ini BEEP (jeda) BEEP (jeda) BEEP BEEP
