Sun Solaris 1.x

Solaris is a Unix based operating system created by Sun Microsystems (now purchased by Oracle in 2010). It is the successor to SunOS and was released initially in June of 1992. The OS is based off of System V Unix and its first release was known internally as SunOS 5. This OS was typically used on SPARC based processors, up until 1994 when it began to support x86 and x86-64 based machines. Versions of Solaris up until version 8 are considered abandoned, with version 9's support ending in October 2014.

The OS has been open-sourced and its successor is OpenSolaris. Oracle still sells Solaris, with the most recent version being 11.2 released in April of 2014.

Release notes

Although Solaris 2 represented a shift in the core architecture, Sun retroactively brought some versions of SunOS under the Solaris 1 name for marketing purposes. The following versions of SunOS and Solaris directly correspond:

SunOS 4.1.1.x <-> Solaris 1.0

SunOS 4.1.2 <-> Solaris 1.0.1

SunOS 4.1.3 <-> Solaris 1.1

SunOS 4.1.3C <-> Solaris 1.1C

SunOS 4.1.3_U1 <-> Solaris 1.1.1

SunOS 4.1.3_U1B <-> Solaris 1.1.1B

SunOS 4.1.4 <-> Solaris 1.1.2

Installation instructions

Note that installing on real hardware may require a SCSI CD drive that supports 512 byte sectors.
