VIA OnChip IDE Device
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:
OnChip 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.
