DECwindows will expect the LCG to be present on the /VLC, but it's not
implemented yet. You might be able to set WINDOW_SYSTEM to 0 to get
around this problem:

>>> B /R5:1 DKAxxx

SYSBOOT> SET WINDOW_SYSTEM 0

SYSBOOT> C

This should prevent DECwindows graphics drivers from being loaded at
system startup. Also update SYS$SYSTEM:MODPARAMS.DAT to reflect this
change in case you run AUTOGEN.
