Automatic data transfer between system memory and IDE device with minimum CPU
intervention. This improves data throughput and frees CPU to perform other tasks.
Legacy mode support allows devices to function in an operating environment that is not USB-
aware.
The integrated peripheral controller contains an IDE interface with support for two IDE channels.
Select Enabled to activate each channel separately. The default value is ―Enabled‖.
Choosing Disabled for these options will automatically remove the IDE Primary Master/ Slave
PIO and/or IDE Secondary Master/Slave PIO items on the menu.
The four IDE PIO (Programmed Input/Output) fields let you set a PIO mode (0-4) for each of the
four IDE devices that the onboard IDE interface supports. Modes 0 to 4 provide successively
increased performance. In Auto mode, the system automatically determines the best mode for
each device.
Select the mode of operation for the IDE drive. Ultra DMA-33/66/100/133 implementation is
possible only if your IDE hard drive supports it and the operating environment includes a DMA
driver. If your hard drive and system software both support Ultra DMA-33/66/100/133, select
Auto to enable UDMA mode by BIOS.
These options are for you to set up SATA mode: IDE, RAID or AHCI.
Use this item to enable or disable the built-in on-chip serial ATA.
