which correspond to different data transfer rates.
[0] [1] [2] [3] [4] Set the PIO mode to Mode 0, 1, 2, 3, or 4.
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.
SMART Monitoring [Auto]
[Auto] Allows automatic selection of the S.M.A.R.T (Smart Monitoring, Analysis,
and Reporting Technology).
[Enabled] Enables the S.M.A.R.T feature.
[Disabled] Disables the S.M.A.R.T feature.
32Bit Data Transfer [Enabled]
[Enabled] 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

transfer of a particular amount of data.
