First steps :
1) before you can use the OS on your MP4, you must be sure you have a compatible MP4 and
you will also need to INSTALL it to your MP4

Compatible MP4 :
   main chip : ak1025 (also known as ATJ2091)
   flash     : 512MB long sector (2048++ bytes) 
   lcd       : 128*160 pixels, 16bit color

INSTALLING the OS will require to install also EFS (electron-file-system). you can keep most of the old data if you really want that but you will need to free up the following
sectors :
 0x3ffff0 : EFS's root-directory entry (if you want a usable filesystem)
 0x000000 .. 0x00800 : for system files - if you want to install OS to mp4
 (the rest is yours)

2) you can instead debug your MP4 anytime, without the need to install OSAK1025 on it !
   you will be using [giveio_bas.exe] to debug the mp4 in any way you want; 
   from reading/writeing sectors,
   trasnferring programs to mp4's RAM
   accesing mp4's I/O ports 
   and lots of others (also you can use MP4's LCD as 2nd monitor for your PC)

3) to be continued ...
