In firmware versions before 3.00, the startup screen uses an orchestral tuning sound with the words "Sony Computer Entertainment" on it. This was replaced with a different tune along with a new startup, featuring the "PS" logo and the new "PlayStation 3" logo in firmware 3.00 and above. Also during game boot, in firmware versions before 3.00, you are greeted with a "PlayStation 3" splash screen, featuring the Sam Raimi Spider-Man style font. This was removed in firmware versions after 3.00 and instead boots directly into the game.

Early PlayStation 3 consoles had the option to install other operating systems, such as Linux or FreeBSD. This feature was removed in later models, as well on the supported models running firmware 3.21, released in March 2010.
PlayStation 2 Support
The very first PlayStation 3 models (CECHA or CECHB) contained a PlayStation 2 Emotion Engine and Graphics Synthesizer to ensure accurate backwards compatibility for PlayStation 2 games. Due to costs, models CECHC and CECHE remove the Emotion Engine while retaining the Graphics Synthesizer, resulting in partially-emulated backwards compatibility. This also caused compatibility issues with some games. Ultimately, all future PlayStation 3 revisions removed PlayStation 2 support entirely, mostly replacing it with the PlayStation Classics line of re-releases.
Early PlayStation 3 consoles also had the ability to play SACD, Sony's fancy upgraded version of the Compact Disc, adding features such as higher bitrates and surround sound. Ultimately, the format was a commercial failure, and Sony would remove SACD support along with PlayStation 2 support on later models due to the format's unpopularity.
