The IBM standard uses a set of 4 values which are: cylinder, head, sector, and size. All bit indexes referenced below are relative to the address marker (0 is the first bit of the address marker, 8 is the start of the byte following the address marker). For the size value, the IBM standard uses the value 0 to describe a 128 byte sector, 1 for 256 bytes, 2 for 512 byes, etc. |
