For user capacities below 66,055,248 sectors (32 GB), inserting the AC jumper
limits the Number of Cylinders field 1 to a value of 16,383, as reported in
IDENTIFY DEVICE data word. This allows software drivers to determine that the
actual capacity is larger than indicated by the maximum CHS, requiring LBA
addressing to use the full capacity.
A summary of these effects for the Quantum Fireball Plus AS drives is shown in
