Welcome to the '''Silicon Graphics''' category! SGI built the high-end 3D graphics workstations and servers that powered Hollywood visual effects, scientific visualisation, and CAD throughout the 1990s and early 2000s. The lineup spans the original IRIS 1000 (1984) through the MIPS-based Indigo, Indy, O2, Octane, Fuel, and Tezro desktops, the refrigerator-sized [[SGI Onyx|Onyx]] visualisation systems, the Origin server family, and the late-1990s Windows NT-based Visual Workstation line. This category collects maintenance, troubleshooting, and recap guides for the SGI hardware line.

Each system features:
* PSU service and capacitor replacement for the Indigo / O2 / Octane chassis
* L1/L2 console diagnostics on Origin, Onyx and Tezro hardware
* Lithium PRAM/RTC battery replacement and Dallas/Benchmarq fixes
* BlueArc / XIO / NUMAlink expansion documentation
