- IRIX was initially developed for SGI systems, starting with the IRIS line of terminals and workstations.
- The earliest common version was 4D1-3.0 in 1988, based on UNIX System V Release 3 with 4.3BSD enhancements.
- IRIX 5.0, released in 1993, incorporated features from UNIX System V Release 4 and introduced ELF-format executables.
- IRIX 6.0, released in 1994, added full 64-bit support.
- The final IRIX release was 6.5.30 in August 2006, with support continuing until at least December 2013.
- Key versions include IRIX 5.3 (last for R3000 CPUs), IRIX 6.2 (first to support all current hardware), and IRIX 6.5.22 (last for many classic systems).
- IRIX 6.5.30 is the final release, suitable for the last MIPS-based Silicon Graphics systems.
- Choosing the right IRIX version depends on system family, processor, graphics hardware, and specific driver requirements.
- Platform-specific releases exist, often not supporting all available hardware at the time.
- Recommendations for specific systems include using the most recent IRIX version possible, with exceptions for older hardware.
