This program is no longer used cause no body uses a floppy… i have to update it to a 32bit program from 16bit… and manipulating a USB will be nice instead of a floppy.
This program displays the boot sector of a floppy drive. The biosdisk function can be used to manipulate a FAT32 hard drive even now. Manipulating a FAT16 and FAT12 are straight forward using absolute disk read and absolute disk write functions provided in Borland’s Turbo C IDE.
I am trying to write a program which will help me play with FAT32 in windows… using WIN32 API…
anyway here is one silly program for the strong hearts…
#include<stdio.h> #include<conio.h> #include<bios.h> struct { char jump[3]; char si[8];//system id int bps;// no of bytes per sector char spc;// no of sectors per cluster int res;// no of reserved area char cof;// no of copies of fat int rde;//no of root directory entries int tos;// total no of sectors char md;// media discriptor int spf;// no of sectors per fat int spt;// no of sectors per track int sides;// no of sides int hs;// no of hidden sectors char rest[482]; }zero; void display_bootsector(); void main() { biosdisk(2,0x81,0,0,1,1,&zero); display_bootsector(); } void display_bootsector() { zero.jump[3]=0; printf("\nJump Instruction\t\t%s",zero.jump); zero.si[8]=0; printf("\nSystem Id\t\t%s",zero.si); printf("\nBytes per sector\t%d",zero.bps); printf("\nSectors per cluster\t%d",zero.spc); printf("\nReserved\t\t%d",zero.res); printf("\nCopies of fat\t\t%d",zero.cof); printf("\nRoot directory entries\t%d",zero.rde); printf("\nTotal no of sectors\t%d",zero.tos); printf("\nMedia discriptor\t%0x",zero.md); printf("\nSectors per fat\t\t%d",zero.spf); printf("\nSectors per track\t%d",zero.spt); printf("\nNo of sides\t\t%d",zero.sides); printf("\nNo of hidden sectors\t%d",zero.hs); printf("\n"); } |
