IDE Primary/Secondary Master/Slave PIO
The four IDE PIO (Programmed Input/Output) fields let you set a PIO
mode (0-4) for each of the four IDE devices that the onboard IDE interface
supports. Modes 0 through 4 provide successively increased performance.
In Auto mode, the system automatically determines the best mode for
each device. The settings are: Auto, Mode 0, Mode 1, Mode 2, Mode 3,
Mode 4.
Primary/Secondary Master/Slave UltraDMA
This option allows the BIOS to decide if the IDE device supports Ultra
DMA modes. If set to Auto, the BIOS will auto-detect the Windows
operating system and HDD specification, and then enable the IDE device
to support Ultra DMA 33/66/100/133 mode accordingly. The settings are:
Auto, Disabled.
