IDE Function Setup
Scroll to IDE Function Setup and press <Enter>. The following screen appears:
OnChip IDE Channel 0/1
The mainboard supports two channel of ordinary IDE interface and one channel of
serial ATA interface. Select "Enabled" to activate each channel separately.
Note: If you do not use the onboard IDE connector, set the Onboard Primary
(Secondary) PCI IDE to "Disabled".
Primary/Secondary Master/Slave UDMA
Select the mode of operation for the IDE drive. Ultra DMA-100/133 implementa-
tion is possible only if your IDE hard drive supports it and the operating environ-
ment includes a DMA driver. If your hard drive and your system software both
support Ultra DMA-100/133, select Auto to enable UDMA mode by BIOS.
Options: Auto, Disabled.
IDE Prefetch Mode
Selecting "Enabled" reduces latency between each drive read/write cycle, but may
cause instability in IDE subsystems that cannot support such fast performance. If
you are getting disk drive errors, try setting this value to Disabled. This field does
not appear when the Internal PCI/IDE field, above, is Disabled.
Options: Enabled, Disabled.
