386BSD

Also known as Jolix, 386/BSD

386BSD (also known as "Jolix") is a Unix-like operating system that was developed by couple Lynne and William "Bill" Jolitz. Released as free and open source in 1992, it was the first fully operational Unix built to run on IBM PC-compatible systems based on the Intel 80386 ("i386") microprocessor, and the first Unix-like system on affordable home-class hardware to be freely distributed. Its innovations included role-based security, ring buffers, self-ordered configuration and modular kernel design.

386bsd - First open source BSD operating system, by William and Lynne Jolitz. All release's are currently inconsistent due to media failures and composing from undated partial copies as I'm able to extract them from drives, tapes, and floppies. Basically, working through boxes of decades old stuff/notes. 0.1/1.0 are self-compiling on small memory systems (<32MB), and virtual machines like QEMU and Virtual Box. So the branches are idiosyncratic WRT time, and 0.1/1.0 are the most useful at the moment (2.0's got the most lapses at the moment). After it all gets sorted out, look for ".x" branch which will deal with the "going forward" stuff (from a second box!).

Development began in 1989 while the Jolitzes were at the University of California, Berkeley's Computer Systems Research Group (CSRG), intended to be a port of BSD to 386-based personal computers. They then contributed the project to the university with some of the work ending up in BSD's Net/2, distributed in 1991. However, when the CSRG scrapped the project and ruled that his work was "university proprietary", Jolitz rewrote the code from scratch, based on the incomplete free code from Net/2. Jolitz also claims that 386BSD was the base of Berkeley Software Design (BSDi)'s commercial BSD/386.
