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.

Routine Description:
|
|
|
|
Main entrypoint of the HW recognizer test. The routine builds
|
|
a configuration tree and leaves it in the hardware heap.
|
|
|
|
Arguments:
|
|
|
|
HeapStart - Supplies the starting address of the configuaration heap.
|
|
|
|
HeapSize - Supplies the size of the heap in byte.
|
|
|
|
ConfigurationTree - Supplies a 32 bit FLAT address of the variable to
|
|
receive the hardware configuration tree.
|
|
|
|
HeapUsed - Supplies a 32 bit FLAT address of the variable to receive
|
|
the actual heap size in used.
|
|
|
|
OptionString - Supplies a 32 bit FLAT address of load option string.
|
|
|
|
OptionStringLength - Supplies the length of the OptionString
|
|
|
|
Returns:
|
|
|
|
None.
