EFI POST Code MAP
The following rules apply to POST code encoding:
Bit 15: 1 – IA64 code being executed, 0 – IA–32 code being executed
Bit 14: 1 – system stopped due to known failure, 0 – progress indication
Bit 13: 1 – fault or trap (no change in module numbers), 0 – normal execution
In the event of a fault or trap, only bit 13 is set to allow fault detection.
Bit 12: Reserved
Bit 11–4: Module type
Bit 3–0: Sub–module type
The module number identifies major modules such as memory, PCI, ACPI, etc. The sub–
module identifies sub–functions such as SPD read in progress, ECC error, and DIMM
mismatch for memory module.
