Setting the Default Boot Flags
Who Should
Set the Boot
Flag
The SET BFLG (boot flag) command lets you define parameters
that the system will use each time it boots. This command
should be used only by developers and other technical users who
need and understand its capabilities. Most users will not need to
change the boot flag setting.
Setting the
Boot Flag
Default boot flags should be preset for the operating system
installed on your system. Consult the VAXstation 4000 Model
90 Service Information for the default boot flag number (a
hexadecimal number of up to 8 characters).
Before halting or turning off your system, see the operating
system documentation for shutdown procedures. If your system
is part of a networked group, do not turn off, halt, or restart the
system without notifying work group members.
To reset the default boot flags:
1.
Put the system in console mode by pressing the halt button
behind the front door of the system unit.
2.
At the console prompt, enter:
>>> SET BFLG
new_default-bootflag-number
Return
Using the Alternate Console Feature
If Monitor
Screen Is Blank
If your monitor is not functioning, you can use the alternate
console feature to run tests. By connecting a terminal to the
printer/communications port, you can run tests on the graphics
board or use the system exerciser to determine the cause of the
monitor problem.
