WinXp startup ᵇᵘᵗ sgi's O² PC

The O² was a pretty darn costly Unix workstation successor of the Indy series, made in 1996 by SiliconGraphics, a manifacturer of high-performance computers with a focus on 3d rendering. Most of their revenue came from gov.t & defense, energy, scientific&technical computing (yes I'm quoting Wikipedia), but chances are you're better aquainted with film CGI effects & pre-rendered videogame promo art (in particular for some Snes&N64 titles). I tend to text-wall, but now I'm struggling... I'll just end this description here.
