Integrated Peripherals

These options display items that define the operation of peripheral compo-
nents on the system's input/output ports.
OnChip IDE Channel 0/Channel 1 (Enabled)
The chipset contains a PCI IDE interface with support to two IDE channels.
Select Enabled to activate the primary/secondary IDE interface. Select Dis-
abled to deactivate the primary/secondary interface.
Primary/Secondary Master/Slave PIO (Auto)
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.
Modes 0 through 4 provide successively increased performance. In Auto
mode, the system automatically determines the best mode for each device.
Primary/Secondary Master/Slave UDMA (Auto)
Ultra DMA/100 implementation is possible only if your IDE hard drive supports
it and the operating environment includes a DMA driver (Windows 95 OSR2 or
a third-party IDE bus master driver). If both of your hard drive and your system
software support Ultra DMA/100, select Auto to enable BIOS support.
IDE Prefetch Mode (Enabled)
The onboard IDE drive interface support IDE prefetching for faster drive ac-
cess. If you install a primary and/or secondary add-on IDE interface, set this
field to Disabled if the interface does not support prefetching.
Init Display First (PCI Slot)
This item is used to determine initial device when system power on.
OnChip USB (V1.1+v2.0)
This should be enabled if your system has a USB installed on the system
board and you want to use it.
