OnChip IDE Channel0/Channel1
The chipset contains a PCI IDE interface with support to two IDE chan-
nels. Select Enabled/Disabled to activate/deactivate the primary/second-
ary IDE interface.
Ø
The Choice: Enabled or Disabled.
IDE Prefetch Mode
The onboard IDE drive interface support IDE prefetching for faster drive
access. If you install a primary and/or secondary add-on IDE interface,
set this field to Disabled if the interface does not support prefetching.
Ø

Primary/Secondary Master/Slave PIO
The four IDE PIO (Programmed Input/Output) fields define a PIO mode
for each of the four IDE devices that the onboard IDE interface supports.
Modes 0 through 4 provide successively increased performance. Select
Auto to make the system automatically determine the best mode for
each device.
Ø
The choice: Auto, Mode 0, Mode 1, Mode 2, Mode 3, or Mode 4.
Primary/Secondary Master/Slave UDMA
Ultra DMA 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, select
Auto to enable BIOS support.
Ø
The choice: Auto or Disabled.
