5.2 Beep Codes 

Fatal errors, which halt the boot process, are communicated through a series of audible 

beeps. For example, if the BIOS POST can initialize the video but an error occurs, an 

error message will be displayed. If it cannot display the message, it will report the error as 

a series of beeps.

Fatal error indicating a serious problem with the system. 

Consult your system manufacturer. Before declaring the 

motherboard beyond all hope, eliminate the possibility of 

interference by a malfunctioning add in card. Remove all 

expansion cards except the video adapter.  

  If the beep codes are generated even when all other 

expansion cards are absent, the motherboard has a serious 

problem. Consult your system manufacturer. 

   If the beep codes are not generated when all other expansion 

cards are absent, one of the add in cards is causing the 

malfunction. Insert the cards back into the system one at a time 

until the problem happens again. This will reveal the 

malfunctioning add in card.

If the system video adapter is an add in card, replace or reseat 

the video adapter. If the video adapter is an integrated part of 

the system board, the board may be faulty.  

Before contacting your vendor or Tyan Technical Support, be sure that you note as much 

as you can about the beep code length and order that you experience. Also, be ready with 

information regarding add in cards, drives and O/S to speed the support process and 

come to a quicker solution.
