The Integrated BMC may generate beep codes upon detection of failure conditions. Beep codes are
sounded each time the problem is discovered, such as on each power-up attempt, but are not sounded
continuously. Codes that are common across all Intel server boards and systems that use same
generation chipset are listed in the following table. Each digit in the code is represented by a sequence
of beeps whose count is equal to the digit.
