"Suppose you have a disk with more than 1024 cylinders. Suppose moreover that you have an operating system that uses the old INT13 BIOS interface to disk I/O. Then you have a problem, because this interface uses a 10-bit field for the cylinder on which the I/O is done, so that cylinders 1024 and past are inaccessible."
