➢
IDE HDD Block Mode
Block mode is also called block transfer, multiple commands, or multiple sectors 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.
➢
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.”
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.
➢
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.
** On-Chip Serial ATA Setting **
SATA Mode
There are these options for you to set up SATA mode: IDE, RAID or AHCI.
