3.7.2 On-Chip IDE Device

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 per-
formance.

3.7.3 On-Chip Serial ATA

Choose the status of serial ATA. The default setting is Auto, which allows
the system to arrange all parallel and serial ATA resources automatically.
The value Disabled will disable the SATA controller. Combined Mode
will combine PATA and SATA, and max of 2 IDE drives in each channel.
Enhanced Mode will enable both SATA and PATA, and max of 6 IDE
drives are supported. The SATA Only means SATA is operating in legacy
mode.

3.7.4 Serial ATA Port0/Port1 Mode

Select the mode for SATA port0 and SATA port1. The choices are Pri-
mary Master, Primary Slave, Secondary Master, Secondary Slave, SATA0
Master and SATA1 Master.

3.7.5 IDE HDD Block Mode

If your IDE hard drive supports block mode, select Enabled for automatic
detection of the optimal number of block read/writes per sector for the
drive.
