Chapter 4: BIOS Setup

On-Chip Primary/Secondary PCI IDE

These fields are used to enable or disable the primary or secondary
IDE controller. The default is Enabled. Select Disabled if you want to
add a different hard drive controller.

IDE Primary Master/Slave PIO and IDE Secondary Master/Slave
PIO

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. Your system supports five modes, 0 (default) to 4, which
primarily differ in timing. When Auto is selected, the BIOS will select
the best available mode after checking your drive.

Auto
The BIOS will automatically set the system according to your hard
disk drive’s timing.
Mode 0-4
You can select a mode that matches your hard disk drive’s tim-
ing. Caution: Do not use the wrong setting or you will have drive
errors.

IDE Primary Master/Slave UDMA and IDE Secondary Master/
Slave UDMA

These fields allow you to set the Ultra DMA in use. When Auto is
selected, the BIOS will select the best available option after checking
your hard drive or CD-ROM.

Auto

The BIOS will automatically detect the settings for you.

Disabled

The BIOS will not detect these categories.
