if `payload_grub_withseabios` and/or `payload_seabios_withgrub` are also turned
on.
The `payload_seabios_grubonly` option, if enabled, creates separate ROM
images alongside regular `seabios_withgrub` ones, where the `grubonly` ones
start SeaBIOS but disable the menu and only ever load GRUB from CBFS, which
then provides the boot for your machine.
The `payload_memtest` entry specifies whether or not MemTest86+ is to be
included in ROM images; it will only be included in ROM images for *text mode*
startup, on x86 machines.
