The motherboard chipset contains a PCI IDE interface with support for two
IDE channels. Select "Enabled" to activate the first and/or second IDE interface.
Select "Disabled" to deactivate an interface if you are going to install a primary
and/or secondary add-in IDE interface.
The Choices: Enabled (default), Disabled.
IDE Primary/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.
IDE Primary/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.
