ovmf.sh

#!/usr/bin/env bash

# Tested on: Ubuntu 18.10.
#
# Outcome: TianoCore logo shows, then after a while we go into an UEFI terminal.
#
# EDK helps implement UEFI, but it does not have the closed source low level parts
# which are left as exercises for the readers.
#
# OVFM implements those blobs for emulators.
