BIOS Setup 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. On-Chip Primary PCI IDE The setting disables/enables the onchip primary PCI IDE interface. IDE Primary Master/Slave PIO The IDE PIO (Programmed Input/Output) fields let you set a PIO mode for the IDE devices that the onboard IDE interface supports.

BIOS Setup
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.
On-Chip Primary PCI IDE
The setting disables/enables the onchip primary PCI IDE interface.
IDE Primary Master/Slave PIO
The IDE PIO (Programmed Input/Output) fields let you set a PIO mode for the
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.
IDE Primary Master/Slave UDMA
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
(Windows ME, XP or a third-party IDE bus master driver). If your hard drive
and your system software both support Ultra DMA/33, Ultra DMA/66, Ultra
DMA/100 and Ultra DMA/133, select [Auto] to enable BIOS support.
*** On-Chip Serial ATA Setting ***
SATA Mode
This setting specifies the SATA controller operation mode.
On-Chip Serial ATA
This setting specifies the function of the on-chip SATA controller.
[Disabled]
Disable SATA controller
[Auto]
Automatically determined by BIOS
[Enhanced Mode]
Enable both SATA and PATA, max. 6 IDE
drives supported
[SATA Only]
SATA operates in legacy mode
SATA Port Speed Settings
This setting controls the speed of the SATA port.
PATA IDE Mode / SATA Port
These settings specify the modes of the PATA & SATA ports.
