# Sibelius ## Identification [[Ozmosis firmware|Ozmosis]] and `OZMTool` belong to the historical macOS-on-PC firmware ecosystem. `Z170XG5.22c` resembles a modified Gigabyte Z170-series BIOS filename. [[Sibelius|Sibelius]] is music-notation software, possibly the Windows application being made to run through Wineskin or the target workload for the Hackintosh. ## Notebook evidence - [[Scanned_20260730-1719#PDF page 47 — Ozmosis tooling and firmware image references|PDF page 47: Ozmosis tooling and firmware image references]] — The page ties a specific firmware image/toolchain to a user application. This is important: the firmware work may not be abstract experimentation; it may be in service of preserving a creative software environment. ## Relationships and overlays The source places this note in a shared evidence cluster with [[Ozmosis firmware|Ozmosis firmware]]. Within the larger collection, this evidence extends [[Vendor-Agnostic Recovery|vendor-agnostic recovery]] and [[Continuity Architecture|continuity architecture]] by showing how software, hardware, identity, and pre-OS control depend on recoverable interfaces. ## Evidentiary status and open leads Locate the original ROM and wrapper, identify the exact motherboard, and document why Sibelius required this stack. ## Source - [[Scanned_20260730-1719|Scanned_20260730-1719]]
