Adaptable storage means if something happens to your primary storage, or a muOS update happens, you will have a backup. [Migrate to Secondary Storage](#migrate) If the device you are using has a secondary storage you will have the option to migrate your content to SD2. Go to Configuration then select Storage. There are several options that can be migrated from SD1 to SD2. This will create the directory on SD2, an…
Another option is to use the Backups feature of the Task Toolkit to restore folders quickly.

You would either need to restore a BIOS backup through Archive Manager or copy your BIOS back into MUOS/bios.

Sorry I misunderstood your question.
I’m sorry, but [we do not provide BIOS](https://community.muos.dev/t/click-here-for-bios-files/36).

That folder with those contents comes on a fresh install of muOS as those bios files are associated with free/open source content. Any BIOS files you added to it will be lost when you reflash unless you put them on your PC first as a backup or put them on a secondary SD card
