The Component Code is an unsigned integer value that is assigned by the build process. The
following tables describe the various ranges of component codes:
The Component Code is assigned to an individual component (or driver) using the
POSTCODE= option in the DSC file. If the value that follows POSTCODE= is a hexadecimal
or decimal number, in the range 0x00-0xdf, then that code will be used with all POST Codes
associated with that driver.
