assumes that there is already a directory

consists of a number files:
of what i/o devices are attached to the system,;
contains a set of interrupt service routines for devices
in building the system; a set of header files which contain
the number of various devices that will be compiled into the system;
and a set of swap configuration files which contain definitions for
the disk areas to be used for swapping, the root file system,
argument processing, and system dumps.
it is necessary to run "make depend" in the directory where the new makefile
reminds you of this when it completes.
If you get any other error messages from
you should fix the problems in your configuration file and try again.
If you try to compile a system that had configuration errors, you
will likely meet with failure.
