@itemize
@item If Coreboot was compiled without CONFIG_STATIC_OPTION_TABLE, it can change
its settings, which are applied after a reboot.
@item It can modify Coreboot images default settings with
@command{nvramtool -C coreboot.rom [...]}.
@item It has various options related to the file format used to store these
settings.
@item It can also read/write the CMOS memory where the Coreboot settings can be
located.
