OnChip IDE Channel 0/1
The chipset contains a PCI IDE interface with support for two IDE channels.
To activate the primary IDE interface select Enabled. If you want to disable
the onboard IDE 1 and/or 2, then select Disabled and this interface will be
deactivated
!
IDE Prefetch Mode
The onboard IDE drive interfaces supports IDE pre-fetching for faster drive
access. If you install a primary and/or secondary add-in IDE interface which
does not support pre-fetching set this field to Disabled.
!
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 sup-
ports. Modes 0 through 4 provide successively increased performance. In
Auto mode, the system automatically determines the best mode for each de-
vice.
!
Primary/Secondary, Master/Slave UDMA
Ultra DMA/66 implementation is possible only if your IDE hard drive supports
it and the operating environment includes a DMA driver (Windows 98 OSR2 or
a third-party IDE bus master driver). If your hard drive and your system
software both support Ultra DMA/66, select Auto to enable BIOS support
.
