## Importing

BIOS files are imported exactly the same as ROMs: [Importing ROMs](https://wiki.provenance-emu.com/using-provenance/importing-roms). When you have the correct BIOS successfully imported they will shown in Settings → Cores or they show as missing/red/required, otherwise you have the wrong files. You need the exact ROMs files matching the MD5 hashes above.

### MD5

Though not required, you can verify the MD5 hashes of your files to be certain. To obtain the MD5 hash of your BIOS files, you can use `md5 [path to file, or drag and drop file here]` in Terminal. Check that it matches the MD5 hash of the file listed above.

Alternatively, BIOS files can be force [uploaded](https://wiki.provenance-emu.com/using-provenance/importing-roms#uploading) manually into `/BIOS/com.provenance.[system]` via WebUI or WebDav (iOS, tvOS) or the Apple Files app (iOS only).
