OnChip IDE Channel1

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

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

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

IDE Primary Slave PIO

IDE Secondary Master PIO

IDE Secondary Slave PIO

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.

Default: Enabled

Default: Auto
