The first step would be either of:

	a) Contact a Linux maillist - try checking http://www.linux.org/
	   for details of how you might get help.

	or

	b) Install NetBSD and ask again (This is a NetBSD maillist, not a
	   Linux one. Both NetBSD & Linux are free versions of unix like
	   operating systems, but if you have a problem with one you are
	   much better off asking on the appropriate list.)
