8.3.6 Remote Access Configuration
Remote access configuration provides the settings to allow remote
access by another computer to get POST messages and send
commands through serial port access.
Remote Access
Select this option to Enable or Disable the BIOS remote access feature.
Note: Enabling Remote Access requires a dedicated serial port
connection. Once both serial ports are configured to dis-
abled, you should set this value to Disabled or it may cause
abnormal boot.
Serial Port Number
Select the serial port you want to use for the remote access interface.
You can set the value for this option to COM1 or COM3.
Note: If you have changed the resource assignment of the serial
ports in Advanced> SuperIO Configuration, you must Save
Changes and Exit, reboot the system, and enter the setup
menu again in order to see those changes reflected in the
available Remote Access options.
