Log:
[FREELDR]: Part 3 of my local changes merging:
- Remove the DiskVtbl functions (machxbox.c) of the XBOX and share them instead with those
of the PC, since they are basically the same.
They just however differ by which 'DiskGetPartitionEntry' function they use. To
cope with this, 'DiskGetPartitionEntry' becomes a pointer
to either the default function 'DiskGetMbrPartitionEntry' (which indeed assumes
a MBR-layout, see partition.c), or the special function
'XboxDiskGetPartitionEntry' in the case of partitionless XBOX disks.
Note that, by the way, partition.c should in the future support GPT-layout disks as
well...
- The boot devices pre-initialization code can also be shared as well, thus getting rid of
'XboxInitializeBootDevices', because we note that
this is exactly what the (old) XBOX version of 'DetectBiosDisks' did at its
beginning.
- But then, we can also share 'DetectBiosDisks' XBOX code with its PC version, and
also *fix* the PC code version as well!
'DetectSystem' and 'DetectBiosDisks' are therefore merged *as they
should be*. Thanks to the boot devices pre-initialization code that has
run before the hardware detection, 'DetectBiosDisks' can just use the cached
information.
- Now we correctly initialize the PC root HW system configuration key: we first create it,
then, after the bios disks (floppies + HDDs) are enumerated
we set the BIOS INT13h disk data to the system key's configuration data.
