Standard Configuration Variables
This section provides a list of the configuration variables that are typically
included in SPARC systems.
Note -
Different OpenBoot implementations might use different defaults or provide
different configuration variables. Use the OpenBoot
printenv
command to display the variables on your virtual machine. See
Display the Current Variable Settings.
The value of a configuration variable can be a number, a string, a true or false flag,
a selection from a set of choices, or one of several other data types, depending on the
particular variable. The stack comment shows the way that information is presented on
the FORTH stack.
