386BSD
386BSD wasfree operating system produced fromBSD derived UNIX operating systems forIntel 80386. 386BSD was developed off4.3BSD NET/2 tapesadditionsallow itrun withoutAT&T source license. It was released on Bastille Day, 1992.Soon afterinitial release386BSD, three groups developed offexisting source. BSD/386 came first, which was laterbecomecommercial BSD/OS. NetBSD developed off386BSD 0.1 release,wasfirst free software organization founded on BSD. This was shortly followed by FreeBSD. While these systems were being developed,Computer Science department atUniversityCalifornia, Berkeley continued development,had progressed4.4BSD.
Development on 386BSD sources would not continuemuch longer. Duelicensing concernsAT&T, some potentially so-called encumbered sources which existed within 386BSD werebe removed from allderived systems, anddevelopment386BSD wasbe stopped. Berkeley subsequently removedNet/2 tapes from distribution,replaced them4.4BSD-Lite, which existed withoutcode that AT&T claimed patents on.
Withdevelopment386BSD halted, FreeBSDNetBSD continuedfree development ofBSD derived operating systems. NetBSD continued their development off ofNET/2 tapes4.4BSD-Lite filling inmost ofencumbered source. FreeBSD resynced nearly all their source4.4BSD-Literebuilt what parts were missing themselves, keeping very little of386BSD code.
Work continues on these 386BSD derived operating systems today, alongseveral derivatives thereof (such as Apple's Darwin OpenBSD).
