OnChip IDE Channel 1
The motherboard chipset contains a PCI IDE interface with support for
one IDE channel. Select “Enabled” to activate the IDE interface.

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 add-in IDE interface, set this option to
“Disabled”.
The Choices: Enabled (Default)
/ Disabled.
Secondary Master/Slave PIO
The IDE PIO (Programmed Input / Output) fields let you set a PIO
mode (0-4) for each of the IDE devices that the onboard IDE interface
supports. Modes 0 to 4 will increase performance progressively. In
Auto mode, the system automatically determines the best mode for
each device.
The Choices: Auto (Default)
/ Mode0 / Mode1 / Mode2 / Mode3 /
Mode4
Secondary 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
