INT 15h (biosdisk) funcion 05
ah = 05
dl = drive (0=A, 1=B, ..., 80h=hd 0, ...)
dh = head number
cx = cylinder/sector (only cylinder is valid)

  CX: c c c c c c c c | C c S s s s s s
   hight 2 bites in cl is most significant bits of cylynder number

es:bx -> pointer to byte array CHSV for each sector
	C - cylinder
	H - header
	S - sector
	V - sector size 0-128; 1-256; 2-512; 3-1024

This is only from manual, and not tested. Please send me any results.
