Error Messages and Beep Codes—Intel Q965 Express Chipset
5.0 Error Messages and Beep Codes
This chapter describes the various progress codes that are reported by the BIOS and
the corresponding LED Codes.
The LED codes are 8-bit quantities and can be used as Port 80 codes if the platform
supports Port 80 capturing device. The higher nibble alone is used for a 4-bit LED.
The Status code driver is responsible for translating the Standard Progress/Error code
into a one-byte value. The particular enumeration scheme is set up so that the Port 80
code values will typically increase during the boot process. The early codes are for
subsystems closer to the processor and the later codes are for peripherals.
Typically, the order of initialization is Processor -> Memory -> Busses -> Output/Input
Devices -> Boot Devices
or
Processor -> Memory -> Recovery -> Busses ->
Output/Input Devices -> Boot Devices
The sequence of POST is platform-specific.
5.1 Speaker
The board-mounted speaker provides audible error code (beep code) information
during POST. For information about the location of the onboard speaker refer to
Figure 1.
5.2 BIOS Beep Codes
Whenever a recoverable error occurs during POST, the BIOS “beep” as described in the
following table, Table 23.
5.3 BIOS Error Messages
