IDE Primary Master/Slave PIO [Auto/Mode0/Mode 1-4]
Each channel has both a master and a slave, making four
IDE devices possible. Because each IDE device may have a
different timing mode (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.
