POST Error Messages and Handling
Whenever possible, the BIOS will output the current boot progress codes on the video screen. Progress codes are 32-bit
quantities plus optional data. The 32-bit numbers include class, subclass, and operation information. The class and subclass
fields point to the type of hardware that is being initialized. The operation field represents the specific initialization activity.
Based on the data bit availability to display progress codes, a progress code can be customized to fit the data width. The
higher the data bit, the higher the granularity of information that can be sent on the progress port. The progress codes may be
reported by the system BIOS or option ROMs.
