OnChip IDE Channel0
Default: Enabled
OnChip IDE Channel1
Default: Enabled
You can use these items to enable or disable the primary (0) and secondary (1)
IDE channels that are built into this mainboard. When one or both channels are
enabled, items appear which allow you to set the PIO (programmable
input/output) mode and the UltraDMA mode for master and slave devices on the
channels. We recommend that you leave these items at the default value Auto.
The system will then automatically use the best performance PIO mode and
UltraDMA mode for each device.
IDE Prefetch Mode
Default: Enabled
The built-in IDE drive interfaces support IDE prefetching for faster drive accesses.
If you use an alternative IDE interface (on an expansion card), disable this field if
the alternate IDE interface does not support prefetching.
IDE HDD Block Mode
Default: Enabled
IDE hard disks can deliver better performance if they use block mode transfer.
Most modern hard disk drives support block mode transfers so this item is
Enabled as a default.
IDE Primary Master PIO
Default: Auto
IDE Primary Slave PIO
Default: Auto
IDE Secondary Master PIO
Default: Auto
IDE Secondary Slave PIO
Default: 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. You can choose Auto, to let the system auto detect which PIO
mode is best, or you can install a PIO mode from 0-4.
