I am taking a course in operating system design and implementation, and 
one of the project assignemnt is to implement MSDOS filesystem support 
for MINIX.  MINIX is another limited version of UNIX clone for the PCs.  

Knowing that Linux already has MS-DOS filesystem support, I thought a 
good place to start would be to look at the source code for the MS-DOS 
filesystem on Linux.  Trying to figure out the concept and the design 
from the source code is extremely slow, and time is a very precisious 
resource.  

I am looking for some kind of design (i.e. algorithms or concepts) for 
the MS-DOS filesystem on Linux.  Basically, what I am looking for is a 
geneal idea of how to get started or how to approach the problem.  
Hints such as how to map between the Linux filesystem to MSDOS FAT 
would be very helpful.  Once I understand the concept, implementation 
part may be much easier.  

I would appreciate some help on this subject.
