¾ 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.
¾ On-Chip Primary/Secondary PCI IDE
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” .
NOTE: 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.
¾ 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.
¾ 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.
*** On-Chip Serial ATA Setting ***
¾ SATA Mode
There are these options for you to set up SATA mode: IDE,
RAID or AHCI.
¾ On-Chip Serial ATA
Use this item to enable or disable the built-in on-chip serial
ATA.
¾ 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.
