Nope. There's no firmware state information saved to disk.
There must be something on disk, because I keep
reading web pages that say things like:
You can create a new image file and add it to the
efi menu with efibootmgr (without, of course,
ever having an example :-).
Anyway, I think I've figured out my major problem
with the USB stick testing I've been doing: The
system I've been testing with apparently only claims
to support UEFI, both GPT partitions and UEFI
installs (even on a msdos partition) fail to work.
Only a traditional msdos partition and BIOS boot
actually works.
