4.6.1 IDE Cable Detect
Some UDMA cables use a hole in the ribbon cable as a cable detect
mechanism to determine if a UDMA IDE or standard IDE cable is
installed. The default setting is “Enabled”.
4.6.2 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.
4.6.3 On-Chip 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.
