Drive
Controller
Configures the serial ATA controller's operating mode. Normal enables the serial ATA controller to operate in its serial ATA native mode only.
Compatible enables the serial ATA controller to operate in serial/parallel ATA combination mode.
Error
Reporting
This setting determines whether hard drive errors are reported or not during system setup.
SATA
Operation
Configures the operation mode of the integrated hard-drive controller.
Normal — The hard-drive controller is configured for native mode. This mode provides the highest drive performance and most flexibility.
Combination — The hard-drive controller is configured for combination mode. This mode enables compatibility with some older operating
systems that do not support SATA drives.
The factory default setting is Normal.
NOTE: Changing this setting affects the order in which drives are listed. However, system setup does not reflect these changes until after a
reboot.
SATA
Reporting
Controls whether hard drive errors for integrated drives are reported during system status. This technology is part of the SMART (Self-
Monitoring Analysis and Reporting Technology) specification.
The options are On or Off. The default setting is Off.
Onboard Devices
Integrated
NIC
You can set the NIC to On (default setting), Off, or On w/ PXE. When the On w/ PXE setting is active (available only for the future boot
process), the computer prompts the user to press <Ctrl><Alt><b>. Pressing this key combination causes a menu to display that allows you
to select a method for booting from a network server. If a boot routine is not available from the network server, the system attempts to
boot from the next device in the boot sequence list.
Integrated
Audio
Enables or disables the onboard audio controller
LPT Port Mode This option sets the operating mode for the built-in parallel port. The settings are Off, AT, PS/2 (default setting), EPP, and ECP.
