A request before solving it:

Dear Student,

This is very easy assignment which requires only the implementation of a given program. This implementation will build your understanding of BIOS interrupt 13H routine more clearly. So, do not paste your solution from any kind of source. Just do and describe what happens and how you tackle the errors if any.


Question:                                                                                                                               Marks 20     


Implement the program of lecture number 27 by using the BORLANDC compiler. File path of this program should be at the root directory of D partition and the file name should be LBA.txt. After the implementation of this program you take a memory dump which shows the successive operation of this program.  Also describe the values of this dump to prove the successive operation and also describes the whole processes of your implementation within few lines.

At the end of this assignment, show the data of your text file “LBA.txt” after the execution of above program.
