BIOS Setup
3.1.4 Integrated Peripherals
The settings on the screen are for reference only. Your version may not be identical
to this one.
3.1.4.1 On-Chip Primary PCI IDE and On-Chip Secondary PCI IDE
These fields allow you to enable or disable the primary and second-
ary IDE controller. Select Disabled if you want to add a different
hard drive controller.
3.1.4.2 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.
