F.1 POST Error Beep Codes
The following table lists the POST error beep codes. Before system video initialization, the BIOS uses these
beep codes to inform users on error conditions. The beep code is followed by a user-visible code on the
POST progress LEDs.

Short beep sounded whenever USB device is discovered in POST
or inserted or removed during runtime.

CPU mismatch error
E5, E6
System halted because a fatal error related to the CPU
family/core/cache mismatch was detected.
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.
