IDE HDD Block Mode
This field allows your hard disk controller to use the fast block mode to
transfer data to and from your hard disk drive.
IDE DMA Transfer Access
Use this field to enable or disable IDE DMA transfer access.
OnChip Primary/Secondary PCI IDE
The integrated peripheral controller contains an IDE interface with
support for two IDE channels. Select Enabled to activate each channel.
IDE Primary/Secondary Master/Slave PIO
These fields allow your system hard disk controller to work faster.
Rather than have the BIOS issue a series of commands that transfer to or
from the disk drive, PIO (Programmed Input/Output) allows the BIOS to
communicate with the controller and CPU directly.
The system supports five modes, numbered from 0 (default) to 4, which
primarily differ in timing. When Auto is selected, the BIOS will select
the best available mode.
IDE Primary/Secondary Master/Slave UDMA
These fields allow your system to improve disk I/O throughput to
33Mb/sec with the Ultra DMA/33 feature
SATA Mode
The setting choices for the SATA Mode are IDE, RAID and AHCI
Mode. Select [IDE] if you want to have SATA function as IDE.
Select [AHCI] for Advanced Host Controller Interface (AHCI) feature,
with improved SATA performance with native command queuing &
native hot plug. Select [RAID] to use SATA as RAID function. RAID
function is supported on the board if it uses ICH6R. Otherwise, it is not
supported.
On-Chip Serial ATA
The default setting of Auto allows the Serial ATA drive to be enabled,
when the system detects one.
