4.6.1 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.

4.6.2 On-Chip Primary/Secondary PCI IDE

If you enable IDE HDD Block Mode, the enhanced IDE driver will be
enabled. Leave IDE HDD Block Mode on the default setting.
