4.2 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.

Troubleshooting BIOS Beep Codes
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.

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.
