[laina]

Please I need help with this one :
Problem statement:
Develop and test a program to read the boot sector of a floppy disk, print the significant parameters therein, find the root directory and print its nonempty entries.  You will need to use the BIOS system calls INT 13H, function 02H (Read a disk sector) and int 21H function 09H (output a string).  You should not be using the open file, etc. system calls.  
PLEASE HELP!!!!!!!!!!  :( :( :( :( :( :( :( :(

You should now have all the knowledge you need. Have a go at making the program and if you have any problems after that, then post the faulty code and we will help you to fix it.
