How bear2305/x86-assemby-fat12 works
This repository is a single-file, 16-bit x86 FAT12 boot-sector example for legacy BIOS systems. Its documented runtime path is BIOS loading the sector, execution reaching an entry point that halts the processor, and disk tools or operating systems recognizing the volume from its BPB. The README describes these behaviors, but no assembly source excerpt was available to verify further control flow.
