So it’s LBA, that is, just a long number like a block number. There's nothing there paint. And the drive registers are so stupid: Sector register -- bits 0..7. The low register of the cylinder is bits 8..15. Cylinder high register -- bits 16..23. Device/head number -- bits 24..27. The older the address, the more significant bits are in that register.
