What to know

eTOP-EPC, eTOP-IPC and eCC industrial PC have integrated serial port that can be configured into BIOS.
This FAQ will drive you through serial ports configuration.

What to do to access BIOS Setup

When the system is powered on, the BIOS will enter the Power-On Self Test (POST) routines. These routines perform various diagnostic checks.

To Enter BIOS Setup, powering on the computer and immediately pressing [Del] button.
Once you enter the AMI BIOS Setup Utility, the Main Menu will appear on the screen. The main menu allows you to select from several setup functions and one exit. Use arrow keys to select among the items and press [Enter] to accept or enter the submenu.

Go to “Advanced” menu, that allows you to configure your system for basic operation and select “Super IO Configuration”.

Here you will be able to enter Serial Ports configuration.
