Figure 4.7: OnChip IDE Device
4.6.3 On-Chip Primary PCI IDE and On-Chip Second-
ary PCI IDE
These fields allow you to enable or disable the primary and secondary
IDE controller. The default is Enabled. Select Disabled if you want to add
a different hard drive controller.
4.6.4 IDE Primary Master/Slave PIO and IDE Second-
ary Master PIO
PIO means Programmed Input/Output. Rather than have the BIOS issue a
series of commands to affect a transfer to or from the disk drive, PIO
allows the BIOS to tell the controller what it wants and then let the con-
troller and the CPU perform the complete task by itself. Your system sup-
ports five modes, 0 (default) to 4, which primarily differ in timing. When
Auto is selected, the BIOS will select the best available mode after check-
ing your drive.
