- Read more information from the registry about the disks detected by
the bios.
- Fixed the detection of disks with a signature of zero (in
AddDiskToList).
- Update always the partition table if the modified flag is set.
- Create an unique disk signature.
- Declared some registry query structures in cmtype.h.
