Internal PCI/IDE (Both)
Use these items to enable or disable the internal PCI IDE channels that are
integrated on the mainboard.
IDE Primary/Secondary Master/Slave PIO (Auto)
Each IDE channel supports a master device and a slave device. These four
items let you assign the kind of PIO (Programmed Input/Output) was used by
the IDE devices. Choose Auto to let the system auto detect which PIO mode
is best, or select a PIO mode from 0-4.
IDE Master/Slave Drive PIO (Auto)
This option allows you to set the PIO (Programmed Input/Output) mode for the
two IDE devices (Master and Slave drives) attached to a particular IDE chan-
nel. Normally you should leave it as Auto and let the BIOS auto-detect the IDE
drive's PIO mode. You should only set it manually for the following reasons:
•
If the BIOS cannot detect the correct PIO mode
•
If you want to try to run the IDE device with a higher PIO mode that
it was designed for
•
If you have overclocked the PCI bus and one or more of your IDE
devices cannot function properly (you can correct the problem by
using a slower PIO mode)
Note: Overclocking the PIO transfer rate can cause loss of data.
Master/Slave Drive UltraDMA (Auto)
This option allows you to enable or disable UltraDMA support (if available) for
the two IDE devices (Master and Slave drives) attached to that particular IDE
channel. Normally, you should leave it as Auto and let the BIOS auto-detect if
the drive supports UltraDMA. If it does, the proper UltraDMA transfer mode
will be enabled for that drive, allowing it to burst data at up to 100MB/s. You
