BIOS Beep Codes
If an unrecoverable hardware problem occurs the computer may emit a number of
beeps from the speaker. These are known as beep codes. The pitch and duration
of the beep codes may vary but there will always be a set number of beeps. These
beeps stem from the BIOS’s initial check on the system and will normally occur in the
first few seconds of power on.
Beeps codes represent a terminal error. If the BIOS detects a terminal error
condition, it outputs an error beep code, halts the POST, and attempts to display a
port 80h code on a POST card’s LED display.
