VARIABLE DESCRIPTION
boot Sets the default boot path.
console Selects the system console.
• Set the console variable to s to enable the terminal connected to the
communications connector as the active console.
• If the console variable is set to anything other than s, the monitor
connected to the graphics module in the lowest-numbered slot is enabled.
If no graphics module is installed and the keyboard is connected, the
monitor is connected to the base system frame buffer. If the system does
not detect a keyboard, even if a graphics option is installed, the terminal
connected to the serial communications connector is the active console,
and no console display will be seen on any of the graphics monitors.

• Set the haltaction variable to b to cause the console to boot after the
console performs the appropriate initialization and self-tests.
• Set the haltaction variable to h to cause the console to halt and attempt
no other action.
• Set the haltaction variable to r to cause the console to restart and then
attempt to boot if the restart operation fails.
