6.1.1 PC BIOS Serial Console
With some operating systems, or in some applications, it is preferable to use a serial terminal as an
operator console device for the board. In other cases, a standard VGA screen and PC keyboard
will be required.
The PP 41x/03x can be configured for operation with either a VGA screen or keyboard or with a
serial console. A board switch selects the console mode, as shown in Figure 6-1 below.
When configured in serial console mode, the PC BIOS firmware will re-direct its output to a serial
port, and similarly will take its input from this port, rather than using the VGA screen and PC
keyboard.
Figure 6-1 Console Switch
The serial line speed used for the Serial Console mode may be selected from the BIOS Setup
screen for Main configuration.
