General notes
mzBIOS is a ready-to-use BIOS implementation compatible with mzBoot, targeting ARM32 and ARM64. On PC-class hardware a BIOS is a given; on ARM the firmware landscape is fragmented per-vendor. mzBIOS exists so that the mz boot path looks the same on ARM as it does on x86 — one firmware contract, drawn once.
Bill of materials — what’s in the box
- ARM32 and ARM64 platform support
- Designed as the POST-and-handoff stage below mzBoot
- Freestanding C with minimal assembly entry points
