PIO
The four IDE PIO 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 increased performance. In
Auto mode, the system automatically determines
the best mode for each device.
On-Chip IDE
First/Second
Channel
The Chipset contains a PCI IDE interface with
support for two IDE channels. Select Enabled to
activate the first and/or second IDE interface.

UDMA
UDMA (Ultra DMA) is a DMA data transfer
protocol that utilized ATA transfer protocol that
utilizes ATA commands and the ATA bus to
allow DMA commands to transfer data ata
maximum burst rate of 33 MB/s. When you
select Auto in the four IDE UDMA fields (for
each of up to four IDE devices that the internal
PCI IDE interface supports), the system
automatically determines the optimal data
transfer rate for each IDE device.
IDE DMA
Transfer Access
This category allows you to enable or disable
DMA transfer access of IDE device (or IDE
HDD)
[Enabled],
[Disabled]
SATA 1/2
Enable/Disable Serial-ATA 1 or Serial-ATA-2.
SATA 1 control port 1 and 3, SATA 2 control
port 2 and 4.
