Troubleshooting BIOS Beep Codes

Table 9. Troubleshooting BIOS Beep Codes

Number of Beeps Troubleshooting Action
1, 2 or 3 Reseat the memory, or replace with known good modules.
4-7, 9-11 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 beep codes are generated even when all other expansion cards are absent, consult your
system manufacturer's technical support.
If 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.
8 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.

BIOS Recovery Beep Codes

In the case of a Bootblock update, where video is not available for text messages to be displayed,
speaker beeps are necessary to inform the user of errors. For beep codes associated with a
Bootblock update refer to the Intel® Server Board SE7520AF2 Technical Product Specification.
