Program to make the boot image of the floppy disk in HEX character

What you have to do is just to take a fresh and new floppy to make the image of its DBR and copy the output of this program from the destination file specified and paste this data in your program. Do some formatting if required. Let us see how it works:

/* Program to make the boot Image of the Floppy Disk In HEX Character */

#include <bios.h>
#include <stdio.h>

int main(void)
{
struct diskinfo_t dinfo;
union REGS regs;
int result,i;
int count=0;
char fname[80];
static char dbuf[512];
FILE *fp;

dinfo.drive = 0x00; /* drive number for A: */
dinfo.head = 0; /* disk head number */
dinfo.track = 0; /* track number */
dinfo.sector = 1; /* sector number */
dinfo.nsectors = 1; /* sector count */
dinfo.buffer = dbuf; /* data buffer */
clrscr();

gotoxy(10,3);cprintf("Enter The File Name And Path To Store The Boot Image in HEX System");
gotoxy(5,5);
gets(fname);

fp=fopen(fname,"wb");

if((fp=fopen(fname,"wb"))==NULL)
{
highvideo();
gotoxy(10,10);cprintf("File Could Not Be created");
getch();
exit(0);
}

/// Initialize the Disk System \\\

for(i=0; i<3; i++)
{
regs.h.ah = 0x00; /* Reset Disk System */
regs.h.dl = 0x00; /* Floppy Disk a: */

int86(0x13, &regs, &regs);
}

gotoxy(10,9); cprintf("Attempting to read from Floppy disk drive :\n");
result = _bios_disk(_DISK_READ, &dinfo);

if ((result & 0xff00) == 0)
{
gotoxy(10,14);
cprintf("Disk read from Floppy disk drive : successful.\n");

while(count<512)
{
fprintf(fp,"0x%X, ",dbuf[count] & 0xff );
count++;
}

fclose(fp);
}

else
{
gotoxy(10,14);
cprintf("Cannot read drive A, status = 0x%02x\n", result);
}
return 0;
}
