BSD/OS

BSD/OS is a proprietaryUnixoperating system first released in 1993 as BSD/386. It was originally developed and sold by Berkeley Software Design, Inc. (BSDi) and designed to be a Unix for 386-based PCs. It was built off the Net/2 distribution of BSD, to which the developers had previously contributed.

Eventually the operating system was also ported to support PowerPC and SPARC architectures, and consequently was retitled to BSD/OS as of version 2.0 (1995). In 2001, BSDi sold the rights of the OS to Wind River Systems who developed and released version 5.0 in 2003 before discontinuing the product.
