In addition, the PIO and DMA modes may be configured for each
SATA hard drive.
PIO Mode
The PIO Mode has six possible settings: Auto, 0, 1, 2, 3, and 4. The
"Auto" setting enables the BIOS to autonomously determine the
appropriate PIO mode for the hard drive. If a manual setting is
preferred, then be sure the correct PIO mode of the hard drive is
used. It is not recommended to set the PIO mode higher than
what the hard drive manufacturer states.
DMA Mode
The DMA Mode has four possible settings: Auto, SWDMAn,
MWDMAn and UDMAn. If a manual setting is preferred, then be
sure the correct DMA mode of the hard drive is used.
Auto
The "Auto" setting enables the BIOS to automatically detect DMA
mode.
SWDMAn
Single Word DMA mode.
MWDMAn
Multi Word DMA mode.
UDMAn
Ultra Word DMA mode.
