6.4.1 IDE Master/Slave PIO/UDMA Mode
IDE Primary (Secondary) Master/Slave PIO/UDMA Mode (Auto) Each channel (Primary
and Secondary) has both a master and a slave, making four IDE devices possible.
Because each IDE device may have a different Mode timing (0, 1, 2, 3, 4), it is necessary
for these to be independent. The default setting “Auto” will allow auto detection to
ensure optimal performance.
