to say, you want to tell the hard disk controller which sector under which head of the hard disk is to be read, and then issue the READ command. The hard disk controller caches the content of the sector, then, the 16-bit data is put into a register (1f0h) in sequence, and the CPU can read the data through the IO command. Let's look at another sample code: MoV dx, 1f6h; disk number and head number to be readMoV Al, 0a0h; disk 0, head 0Out dx,
