Primary Master/Slave UDMA
Ultra DMA function can be implemented if it is supported by the IDE hard
drives in your system. As well, your operating environment requires a DMA
driver (Windows 95 or OSR2may need a third party IDE bus master driver). If
your hard drive and your system software both support Ultra DMA, select Auto
to enable BIOS support.
The Choices: Auto (default), Disabled.
IDE DMA Transfer Access
This item allows you to enable or disable the IDE DMA transfer access.
The Choices: Enabled (default), Disabled.
Serial-AT A Controller
Enables support for Serial-ATA controller.
The Choices: All Enabled (default), Disabled
IDE Prefetch Mode
The “onboard” IDE drive interfaces supports IDE prefetch function for faster
drive access. If the interface on your drive does not support prefetching, or if
you install a primary and/or secondary add-in IDE interface, set this option to
“Disabled”.
The Choices: Enabled (default), Disabled.
