Changing Startup and Boot Defaults
You can change the way the system starts up or boots the operating system. For example,
you can set the system to autoboot or you can change the default boot device. To make
these kinds of changes you need to change default values for your system's environment
variables.
•
To change default values for Windows NT systems, which boot automatically, you
can prevent autoboot by selecting one of the menu options.
•
To change default values for DEC OSF/1 or OpenVMS systems, see "set" in Table 4-
1, "Basic SRM Console Commands."
Startup and Boot Environment Variables
The following environment variables affect the way the system starts up or boots:
•
auto_action
•
autoload
•
countdown
•
