Starting sector and
cylinder number */
unsigned char parttype ; /* File system
Indicator Byte */
unsigned char end_side ; /* Ending Head */
unsigned int end_sec_cyl ; /* combination of
Starting sector and
cylinder number */

unsigned long part_beg ; /* Relative Sector Number */
unsigned long plen ; /* Partition length in sectors */
} ;

/* Structure to read MBR */

struct part
{
unsigned char master_boot[446] ; /* IPL (Initial
Program Loader)*/
struct partition pt[4] ; /* Partition table */
int lasttwo ; /* Magic Number */
} ;

struct part p ;

void main()
{
clrscr();

/* Read First Sector of first hard disk */

biosdisk ( 2, 0x80, 0, 0, 1, 1, &p ) ;
