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 four 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 / 98 / NT /
2000 OSR2 or a third-party IDE bus master driver).
➤
Auto: If your hard drive and your system software both support Ultra DMA/66, select
Auto to enable BIOS support. For Ultra DMA/100 devices, please refer the
requirements mentioned in page 2-15. (Default setting)
➤

this item.
