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
, RSC, 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 88.
