Using BIOS
Primary/Secondary Master/Slave PIO (Auto)
Each IDE channel supports a master device and a slave device. These four items let you
assign which kind of PIO (Programmed Input/Output) is used by 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 and improves the speed of access to IDE devices.
