Reference for System Console OpenBoot Variable Settings

Certain OpenBoot configuration variables control from where system console input is taken and to where its output is directed. The table below shows how to set these variables in order to use ttya, the system controller, or a local graphics terminal as the system console.

1 – POST output will still be directed to the serial port, as POST has no mechanism to direct its output to a graphics terminal.

2 – If the system detects no local graphics terminal, it directs all output to (and accepts input from) the serial port.

In addition to the above OpenBoot configuration variables, there are other variables that determine whether and what kinds of diagnostic tests run. These variables are discussed in “Controlling POST Diagnostics” on page 82.
