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. Class and subclass point to the type of the hardware that is
being initialized, where as the Operation field represents the specific initialization activity. Based
upon the data bit availability to display Progress Code, a progress code can be customized to fit
the data width. The higher the data bit, higher the granularity of information, which could send
on the progress port. The progress codes may be reported by system BIOS or option ROMs.
