A free software version of the bsd unix operating system originally derived from the generally available parts of the "berkeley net release/2". William Jolitz played a key rôle and there have been many contributors. Many new and innovative features have been added to 386BSD since its original release in June 1992. An unofficial patchkit, available from many anonymous ftp archives, solves many of the problems associated with 386BSD Version 0.1. In addition, many common Unix packages have been ported.
386BSD has been superseded by freebsd and netbsd.
