About BIOS setup
The BIOS (Basic Input and Output System) Setup program is a menu driven utility that enables you to make
changes to the system configuration and tailor your system to suit your individual work needs. It is a ROM-
based configuration utility that displays the system’s configuration status and provides you with a tool to set
system parameters. These parameters are stored in non-volatile battery-backed-up CMOS RAM that saves this
information even when the power is turned off. When the system is turned back on, the system is configured
with the values found in CMOS.
How to get to BIOS Setup
At first connect the keyboard to the Panel PC. Powering on the computer and immediately pressing <Del> key
allows you to enter Setup. Press the <Del> key to enter Setup. Navigate to the Serial Port Configuration (see
picture bellow) and setup the requested mode and interface parameters. Then exit the BIOS setup with saving
the changes.
