Jenis beep code bios dan artinya

Secara umum ada 4 produsen yaitu AMI BIOS,AWARD BIOS,PHONIX BIOS serta MAC BIOS untuk komputer pruduksi Apple yang mengunakan sistem operasi macintosh.

BERIKUT TABEL PENJELASAN MASING MASING BIOS.



1. AMI BIOS

• 1 bunyi beep pendek = DRAM refresh failure
• 2 bunyi beep pendek = Parity circuit failure
• 3 bunyi beep pendek = Base 64K RAM failure
• 4 bunyi beep pendek = System timer failure
• 5 bunyi beep pendek = Process failure
• 6 bunyi beep pendek = Keyboard controller Gate A20 error
• 7 bunyi beep pendek = Virtual mode exception error
• 8 bunyi beep pendek = Display memory Read/Write test failure
• 9 bunyi beep pendek = ROM BIOS checksum failure
• 10 bunyi beep pendek = CMOS shutdown Read/Write error
• 11 bunyi beep pendek = Cache Memory error
• 1 bunyi beep panjang, 3 beep pendek = Conventional/Extended memory failure
• 1 bunyi beep panjang, 8 beep pendek = Display/Retrace test failed  

2. AWARD BIOS

• 1 beep panjang, 2 beep pendek mengindikasikan terjadi kesalahan pada video dan bios tidak dapat mendeteksi komponen video untuk menampilkan informasi pada monitor 
• bunyi beep lainnya mengindikasikan terjadi kesalahan memory. 
• Jika ada kesalahan lainnya bios akan menampilkannya di layar. 

3. IBM BIOS

• Tidak ada bunyi beep = Tidak ada tegangan power supply,Memory
  Card,VGA card,Sound Card,LAN Card ada yang
  longar/belum terpasang dengan benar, hubung
  singkat.  
• 1 beep pendek = Normal POST, Komputer booting dengan baik.
• 2 beep pendek = Terjadi kesalahan POST,error kode ditampilkan di
  monitor.
• Beep terus menerus = Tidak ada tegangan power supply,Memory
  Card,VGA card,Sound Card,LAN Card ada yang
  longar/belum terpasang dengan benar, hubung
  singkat.
• Beep pendek berulang = Tidak ada tegangan power supply,Memory
  Card,VGA card,Sound Card,LAN Card ada yang
  longar/belum terpasang dengan benar, hubung
  singkat.  
• 1 beep panjang dan 1 beep pendek = Mengidentifikasikan ada masalah pada motherboard
• 1 beep panjang dan 2 beep pendek = Masalah pada VGA (bagian video CGA/mono)
• 1 beep panjang dan 3 beep pendek = Masalah pada VGA (bagian video EGA)
