If you highlight the literal “Press Enter” next to the “VIA Onchip
IDE Device” label and then press the enter key, it will take you a
submenu with the following options:
IDE Channel 0/1
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 Prefetch Mode
The “onboard” IDE drive interfaces supports IDE prefetching for
faster drive access. If the interface does not support
prefetching. If you install a primary and/or secondary add-in IDE
interface, set this option to “Disabled”.
The Choices: Enabled (default), Disabled.
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 increased performance
progressively. In Auto mode, the system automatically
determines the best mode for each device.
The Choices: Auto (default), Mode0, Mode1, Mode2, Mode3,
Mode4.
Primary / Secondary /Master / Slave UDMA
Ultra DMA/100 functionality 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
OSR2 or a third party IDE bus master driver). If your hard drive
and your system software both support Ultra DMA/100, select
Auto to enable BIOS support.
The Choices: Auto (default), Disabled.
