Azalia Controller
If optional audio kit AX93242 is plugged in, please Enable it.
IDE HDD Block Mode
Block mode is also called block transfer, multiple commands, or multiple sector read/write. If
your IDE hard drive supports block mode (most new drives do), select Enabled for automatic
detection of the optimal number of block read/writes per sector the drive can support.
IDE DMA transfer access
Automatic data transfer between system memory and IDE device with minimum CPU
intervention. This improves data throughput and frees CPU to perform other tasks.
IDE Primary/Secondary Master/Slave PIO
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.
IDE Primary/Secondary Master/Slave UDMA
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.
SATA Mode
There are these options for you to set up SATA mode: IDE, RAID or AHCI.
LEGACY Mode Support
Legacy mode support allows devices to function in an operating environment that is not
USB-aware.
