Since modern PCs use 32-bit I/O buses such as the PCI bus, doing 16-bit
transfers is a waste of half of the potential bandwidth of the bus. Enabling
32-bit access in the BIOS (if available) causes the PCI hard disk interface
controller to bundle together two 16-bit chunks of data from the drive into
a 32-bit group, which is then transmitted to the processor or memory. This
results in a small performance increase.
