OnChip IDE Channel0/Channel1
( Default setting : “Enabled” )
The 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 install a primary and/or secondary add-in IDE
interface.
IDE Prefetch Mode
( Default setting : “Enabled” )
The onboard IDE drive interfaces supports IDE prefetching, for faster drive
accesses. If you install a primary and/or secondary add-in IDE interface, set this
field to
Disabled
if the interface does not support prefetching.
Primary/Secondary Master/Slave PIO:
( Default setting : “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:
( Default setting : “Auto” )
Ultra DMA/33 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 your hard drive and your system software
both support Ultra DMA/33, select Auto to enable BIOS support.
The Choice: Auto, Disabled
