# A simple script to run an archiso image using qemu. The image can be booted
# using BIOS or UEFI.
#
# Requirements:
# - qemu
# - edk2-ovmf (when UEFI booting)


set -eu

print_help() {
    cat << EOF
Usage:
    run_archiso [options]

Options:
    -b              set boot type to 'bios' (default)
    -h              print help
    -i [image]      image to boot into
    -s              use secure boot (only relevant when using UEFI)
    -u              set boot type to 'uefi'

Example:
    Run an image using UEFI:
    $ run_archiso -u -i archiso-2020.05.23-x86_64.iso
