Question

Can anyone help me??

Answer 1

BOOL ReadSect(BYTE disk, int nsects,DWORD lsects,void* data)
{
union REGS iregs, oregs;
struct SREGS sregs;

iregs.h.ah = 0×02;
iregs.h.al = nsects;
iregs.x.bx = FP_OFF (data);
sregs.es = FP_SEG (data);
iregs.h.ch = (BYTE) track;
iregs.h.cl = (BYTE) sector;
iregs.h.dh = (BYTE) head;
iregs.h.dl = disk;

int86x (0×13, &iregs, &iregs, &sregs);

if (iregs.x.cflag)
Return FALSE;
Else
Return TRUE;
}
