ddr_config will take the default input file, ddr.dbase, and build
a new device database. This is effective immediately, and
there is no need to rebuild the kernel.
Note: ddr.dbase is a unix shell script and is not written in
C. This means # is used to signify a comment, not /* and
*/ or //, as used in C. Make sure any comments included
in this file are preceded with the # character.
Digital UNIX Versions earlier than 4.0.
