--------------- Notes --------------------------------------------------
This code allows browsing of FAT32 formatted IDE hard discs.
The board that it was tested on is the EDTP IDE Interface Board with 
Network Connection... see http://www.edtp.com/
The board consists of a Atmega128 with 1Mbit of SRAM attached. In this code 
the external SRAM is not used or required.

I developed this code on ICC AVR V6, and to enable it to function correctly 
I had to adjust the ammount of return stack that is assigned, this is located in 
project settings (change to 50 to be safe).


Certain assumptions have been made in the code, due to time restrictions 
and *lazyness*. You can however change this code to work on other configurations 
of hardware, please send me a copy if you do :-)


The code contained in drivers.c is very board specific, also XTAL specific...

Please refer to my website for 'class diagram' type overviews of the softwares construction.
