Using BIOS
IDE DMA transfer access (Enabled)
This item allows you to enable the transfer access of the IDE DMA then burst onto the
PCI bus and nonburstable transactions do not.
OnChip IDE Channel0/1 (Enabled)
Use this item to enable or disable the PCI IDE channels that are integrated on the
motherboard.
IDE Prefetch Mode (Enabled)
The onboard IDE drive interface supports IDE prefetching, for faster drive access. If you
install a primary and secondary add-on interface, set this field to Disable if the interface
does not support prefetching.

Primary/Secondary Master/Slave PIO (Auto)
Each IDE channel supports a master device and a slave device. These four items let you
assign the kind of PIO (Programmed Input/Output) was used by the IDE devices. Choose
Auto to let the system auto detect which PIO mode is best, or select a PIO mode from 0-
4.
Primary/Secondary Master/Slave UDMA (Auto)
Each IDE channel supports a master device and a slave device. This motherboard
supports UltraDMA technology, which provides faster access to IDE devices.
If you install a device that supports UltraDMA, change the appropriate item on this list
to Auto. You may have to install the UltraDMA driver supplied with this motherboard in
order to use an UltraDMA device.
IDE HDD Block Mode (Enabled)
Enable this field if your IDE hard drive supports block mode. Block mode enables BIOS
to automatically detect the optimal number of block read and writes per sector that the
drive can support. It also improves the speed of access to IDE devices.
