SATA Mode
This allows you to set RAID mode for Serial ATA devices. Refer to section 5
for more RAID information.
Options: RAID, IDE.
IDE DMA transfer access
Automatic data transfer between system memory and IDE device with minimum
CPU intervention. This improves data throughput and frees CPU to perform other
tasks.
Options: Enabled, Disabled.
OnChip IDE Channel0/1
The mainboard supports two channel of ordinary IDE interface. Select “Enabled”
to activate each channel separately.
Options: Enabled, Disabled.
Note: If you do not use the onboard IDE connector, set the Onboard Primary PCI
IDE and Onboard Secondary PCI IDE to “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.
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 supports. Modes 0 to 4
provide successively increased performance. In Auto mode, the system automati-
cally determines the best mode for each device.
Options: Auto, Mode 0 ~ 4.
Primary/Secondary Master/Slave UDMA
Select the mode of operation for the IDE drive. Ultra DMA-33/66/100/133
implementation is possible only if your IDE hard drive supports it and the
operating environment includes a DMA driver. If your hard drive and your
