IDE Primary/Secondary Master/Slave PIO
Each of these four items sets the mode timing according to the IDE hard disk
drives in your system. PIO means Programmed Input/Output. Rather than have
the BIOS issue a series of commands to effect a transfer to or from the disk
drive, PIO allows the BIOS to tell the controller what it wants and then let the
controller and the CPU perform the complete task by themselves. This is simpler
and more efficient (and faster). PIO mode concerns data transfer rate. It can be
mode 0 to 4. Higher number indicates faster rate.
The available options are
0
,

,

, and
Auto
. Check with your dealer to know
the PIO mode supported by your hard disk drive. Selecting
Auto
will allow auto-
detection to ensure optimal performance.
IDE Primary/Secondary Master/Slave UDMA
These items set if the IDE hard disk drive supports UDMA (Ultra 33 synchronous
DMA mode transfer).
The available options are
Auto
and
Disabled
. Check with your dealer to know if
your hard disk drive supports UDMA.
On-Chip Primary/Secondary PCI IDE
As stated above, your system includes two built-in IDE controllers, both of which
operate on the PCI bus. The item allows you either to enable or disable the
controller.
The available options are
Enabled
and
Disabled
. Select
Disabled
only if you are
using higher performance or specialized controller card instead of the onboard
IDE controller.
