So what's wrong with using DOS to update firmware? DOS is a small and simple program loader that's unlikely to require much in the way of hardware to work and is unlikely to be infected by a virus in today's world.
Honestly, I've tried to use a .EXE to update the BIOS on my personal system, and I never was able to find a bootable FreeDOS image that could run it from a USB boot disk. Who has floppy disks anymore? I don't even have a CDROM drive. I never ran DOS so I honestly have no clue what I'm doing with it.
Fortunately, newer hardware let me drop the executable in the EFI volume for updates.
Would you rather have to boot a mulit-gigabyte image of who-knows-what that does ghawd-knows-what for what should be simple task?
It's not a simple task. Do it wrong, and you've bricked your system.
