You can load a filesystem driver to gain access to files on a filesystem other than FAT (or HFS+ or APFS on Macs or ISO-9660 or NTFS on some systems).At the moment, EFI drivers are few and far between but you can or might want to use them for various reasons: Why Should You Use EFI Drivers?ĮFI supports drivers, which can activate hardware or filesystems in the pre-boot environment. I have not tested this feature, so I don't know how well it works. Note: The Linux efibootmgr tool provides an option, -r, that enables it to install EFI drivers rather than EFI boot loader binaries.

This page tells you why you might want to use drivers, how you can install and use rEFInd's own drivers, where you can go to find other drivers, and provides tips on a few specific drivers. Thus, if you want to use EFI drivers, rEFInd's ability to do so can be useful. Although EFI implementations should be able to load drivers prior to rEFInd's launch, in my experience, most EFI implementations offer such poor control over EFI driver loading that they can't be counted on to do this.
