Purpose
[Disabled]
This option disables BIOS from using the Multi-Sector Transfer
mode on the current channel. Data to/from the device will be
transmitted one sector per unit of time.
PIO Mode
Programmed I/O (PIO) mode
[Auto]
This option allows BIOS to automatically determine if the device
supports the PIO mode. This setting is recommended to be
used when it is impossible to determine the supported mode of
the connected device.
[0]
Set the PIO 0 mode for the connected device. The data transfer
rate in this mode is up to 3.3 MB/sec.
[1]
Set the PIO 1 mode for the connected device. The data transfer
rate in this mode is up to 5.2 MB/sec.
[2]
Set the PIO 2 mode for the connected device. The data transfer
rate in this mode is up to 8.3 MB/sec.
[3]
Set the PIO 3 mode for the connected device. . The data
transfer rate in this mode is up to 11,1. MB/sec.
[4]
Set the PIO 4 mode for the connected device. The data transfer
rate in this mode is up to 16.6. MB/sec.
DMA Mode
DMA (Direct Memory Access) data transfer mode
[Auto]
Recommended value for the most efficient data transfer. BIOS
will automatically detect the most suitable DMA mode.
[SWDMA0]
[SWDMA1]
[SWDMA2]

Smart Monitoring, Analysis, and Reporting Technology
[Auto]
BIOS will automatically detect and support the connected
device. It is recommended to use this option if detection and
support of the connected drive is impossible.
[Enabled]
This option enables BIOS to use the SMART function when
working with the connected drives
[Disabled]
This option disables BIOS from the use of SMART function when
working with the connected drives.
32-bit Data Transfer
32-bit data transfer mode
[Enabled]
This option enables the use of 32-bit data transfer for the
connected device.
[Disabled]
This option disables the use of 32-bit data transfer for the
connected device.
