e7f0852dbd correct sectors/track, head and hidden sector values if the boot sector 
disagrees with the default bpb (unless the default bpb says that the
number of hidden sectors is zero (usual for floppies)).

(inclusive locking)

5567aba08b Fixed bug #1722: dir_close() was called for normal files (via map_cluster 
and find_fat_free). This completely messed up rwblock. Removed these calls
(for directories they are already covered at a higher level) and added
a few sanity checks to dir_close and dir_write.

4f1a117069 * FAT32 kernels should ignore the upper word of the cluster number for 
FAT16 partitions (just like FAT16 kernels do)
* added extra checks to make sure that invalid FAT entries are never
  followed
* made put_console() public to be able to print a message in case of
  FAT corruption
* some small optimizations and header cleanups (some suggested by Arkady)

8db46073f9 From: Eric Luttmann <ecl@users.sourceforge.net> 
Fix for multisegmented device drivers: If there are multiple device
drivers in a single driver file, only the END ADDRESS returned by the
last INIT call should be the used.  It is recommended that all the
device drivers in the file return the same address.
This fixes a load problem with DUSE.
