Module Name:
hwdetect.c
Abstract:
This is the main hardware detection module. Its main function is
to detect various system hardware and build a configuration tree.
N.B. The configuration built in the detection module will needs to
be adjusted later before we switch to FLAT mode. The is because
all the "POINTER" is a far pointer instead of a flat pointer.
