AL = number of sectors
CH = low eight bits of cylinder number
CL = sector number (bits 5-0)
high two bits of cylinder number (bits 7-6)
DH = head number
DL = drive number (80h = first, 81h = second)
ES:BX -> data buffer
Return: CF clear if successful
CF set on error
AH = status (see AH=01h)
AL = number of sectors transferred
