3.6 Integrated Peripherals
Choose this option and the following display appears.
• • • • • On-Chip Primary/Secondary IDE
The chipset contains a PCI IDE interface which supports two IDE channels. Select "Enabled"
to activate the first and/or second IDE interface. Select "Disabled" to deactivate this interface,
if you install a primary and/or secondary add-in IDE interface.
• • • • • Primary/Secondary Master/Slave PIO
The four IDE PIO (Programmed Input/Output) fields let you set a PIO mode (0-4) for each of
the four IDE devices that the onboard IDE interface supports. Mode 0 through 4 provide
successively increased performance. In "Auto" mode, the system automatically determines
the best mode for each device.
• • • • • Primary/Secondary Master/Slave Ultra DMA
Ultra DMA/33(66) implementation is possible only if your IDE hard drive can support it and
the operating environment includes a DMA driver (Windows 95 OSR2 or a third-party IDE
bus master driver). If both your hard disk drive and your system software can support Ultra
DMA/33(66), select "Auto" to enable BIOS support.
