The program shows the example of use of functions int86 and int86x functions. In this Program the int86 function is initializing the disk by resetting the disk system, using function 00H of INT 13H. The int86x function is verifying every sector of the floppy (1.44Mb, 3½ floppy disk) from both sides, up to 0 to 79 tracks ( total 80 tracks) using the function 04H of INT 13H.
