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 / ME / NT / 2000 or a
third-party IDE bus master driver).
Auto:
If your hard drive and your system software both support Ultra DMA, select Auto to enable BIOS
support.
Disabled: If you encounter a problem in using Ultra DMA devices, you can try to disable this item.
