Good luck FreeDOS probably was required to update a PC BIOS, the time when I didn't use a PC, but a C64 or Atari ST. IOW that was a long, long time ago. I'm not aware of any 64 bit architecture PC, that requires more than a FAT 32 formatted device, to update the BIOS or UEFI thingy. IIRC I even updated a decades old 32 bit machine, just by using a FAT 32 partition. That time the computer just supported PATA (IDE), no SATA and I still used a floppy disk for some purposes. AFAIK updates on even relatively aged machines doesn't require an operating sytsem at all, it could be done by the BIOS and a FAT 32 partitioned device. It's just important to read the vendor's hints. Sometimes updating from a very old release to the latest release might brick the machine, it might be required to upgrade from one release to another and IIRC sometimes it could be impossible to downgrade, if an upgrade should suffer from a regression.
