Daha152x.rst130 The number of cylinders/heads/sectors is called geometry and is required
146 namely the address space is limited to up to 255 heads, up to 63 sectors
149 The AHA-1522 BIOS calculates the geometry by fixing the number of heads
157 extended translation. This means that the BIOS uses 255 for heads,
