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.
The settings are: Disabled, Enabled (default).
PATA DMA Mode
Force IDE device to work in DMA33 or DMA66/100 mode.
Auto
( Default )
By system determine automatically.
DMA33
Work in DMA 33 mode.
DMA66/100
Work in DMA 66/100 mode.
Note: That is supported fastest speed by IDE device to determine in DMA66 or DMA100.
OnChip Serial SATA
That it has 4 choices as below:
Disabled
Disable SATA Controller.
Combined Mode
PATA and SATA are combined.
Max of 2 IDE drives in each channel.
Enhanced Mode
( default )
Enable both SATA and PATA.
Max of 6 IDE drives are supported.
SATA Only
SATA is operating in legacy mode.
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 through 4 provide
successively increased performance. In Auto mode, the system automatically determines
the best mode for each device.
The settings are: Auto (default), Mode 0, Mode 1, Mode 2, Mode 3 and Mode 4.
Primary/Secondary Master/Slave UDMA
Ultra DMA/33 implementation is possible only if your IDE hard drive supports it and the
operating environment includes a DMA driver (Windows 95 OSR2 or a third-party IDE bus
master driver)You’re your hard drive and your system software both support Ultra DMA/33
and Ultra DMA/66, select Auto to enable BIOS support.
Settings are: Auto(default) , Disabled.
OnChip IDE Primary/Secondary
The integrated peripheral controller contains an IDE interface with support for two IDE
channels.
Select Enabled to activate each channel separately.
Settings are: Enabled (default), Disabled.
