Table 2-4. Onboard Devices Options

Option

Description

 

 

Integrated NIC

Enables or disables the integrated Network Interface Controller (NIC). Off

(On default)

disables the controller. On enables the controller. On w/PXE enables the

controller with PXE. On w/RPL enables the controller with RPL.

 

 

NOTE: PXE or RPL is required only if you are booting to an operating system

 

on another system, not if you are booting to an operating system on a hard

 

drive in this system.

 

 

USB Controller

Enables or disables the internal USB controller. Off disables the

(On default)

controller. On enables the controller. No Boot enables the controller, but

disables the ability to boot from a USB device.

 

 

NOTE: Operating systems with USB support will recognize USB storage

 

devices regardless of the No Boot setting.

 

 

Front USB Ports

Enables or disables the front USB ports independently of the rear ports. Off

(On default)

disables the controller. On enables the controller. No Boot enables the

controller, but disables the ability to boot from a USB device.

 

 

NOTE: Operating systems with USB support will recognize USB storage

 

devices regardless of the No Boot setting.

 

 

Serial Port #1

Serial Port 1 options are COM1, COM3, Auto, and Off.

(Auto default)

When serial port 1 is set to Auto, the integrated port automatically maps

 

to the next available port. Serial port 1 attempts to use COM1 first and

 

then COM3. If both addresses are in use for a specific port, the port is

 

disabled. When serial port is set to COM1, the integrated port is

 

configured at 3F8h with IRQ4. When the serial port is set to COM3, the

 

integrated port is configured at 3E8h with IRQ4.

 

If you set the serial port to Auto and add an expansion card with a port

 

configured to the same designation, the system automatically remaps the

 

integrated port to the next available port designation that shares the

 

same IRQ setting.
