  While cleaning out some old papers, I came across a brief email from lhdadmin@datapower.com congratulating me on registering at the Linux Hardware Database. The email was dated July 4, 1999.

Very simple. Very cool. For all the potential options, open  /usr/bin/hw-probe  in a text editor. RESOURCES Linux Hardware Database
