DMA Mode [Auto]
DMA (Direct Memory Access) allows your computer to transfer data to and from
the hardware devices installed with much less CPU overhead.
The DMA mode consists of SDMA (single-word DMA), MDMA (multi-word DMA),
and UDMA (Ultra DMA). Setting to [Auto] allows automatic selection of the DMA
mode, or you can select from the following options: [SWDMA1] [SWDMA2]
[MWDMA0] [MWDMA1] [MWDMA2] [UDMA0] [UDMA1] [UDMA2] [UDMA3]
[UDMA4] [UDMA5]

When set to [Auto], the data transfer from and to the device occurs
multiple sectors at a time if the device supports multi-sector
transfer feature.
When set to [Disabled], the data transfer from and to the device
occurs one sector at a time.
Allows automatic selection of the PIO (Programmed input/output)
modes, which correspond to different data transfer rates.
Set the PIO mode to Mode 0, 1, 2, 3, or 4.
Allows automatic selection of the S.M.A.R.T (Smart Monitoring,
Analysis, and Reporting Technology).
Enable the S.M.A.R.T feature.
Disable the S.M.A.R.T feature.
Sets the IDE controller to combine two 16-bit reads from the hard
disk into a single 32-bit double word transfer to the processor. This
makes more efficient use of the PCI bus as fewer transactions are
needed for the transfer of a particular amount of data.
Disable this function.
