Onboard IDE-1 Controller:
The onboard IDE 1 controller can be set as Enabled or Disabled. The default setting is
Enabled
. The
integrated peripheral controller contains an IDE interface with support for two IDE channels. If you
choose
Disabled
, it will effect the settings of four items not available. For example, if you disabled the
Onboard IDE-1 Controller
, you will also disable the
Master/Slave Drive PIO Mode
and
Master/Slave
Drive Ultra DMA
.
Master/Slave Drive PIO Mode:
Six options are available: Auto
)
Mode 0
)
Mode 1
)
Mode 2
)
Mode 3
)
Mode 4. The five IDE
PIO (Programmed Input/Output) items 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 (default setting), the system automatically determines the best mode for each device.
Master/Slave Drive Ultra DMA:
Two options are available: Auto and Disabled. The default setting is
Auto
. Ultra DMA is a DMA data
transfer protocol that utilizes ATA commands and the ATA bus to allow DMA commands to transfer data
at a maximum burst rate of 100 MB/sec.
Ultra DMA/33 or Ultra DMA/66/100 implementation is possible only if your IDE hard drive supports it
and the operating environment includes a DMA driver (Windows
®
95 OSR2 / 98 / NT / 2000 or a third-
party IDE bus master driver).
