We need a seabios support:

commit 54ae5436df92c8caf0a814a7c653adb1d75a084c
Author: Kevin O'Connor <kevin>

    boot: Support "halt" in the boot order to prevent default boot attempts.
    
    Current seabios will attempt to boot from both configured devices and
    a list of default devices.  Sometimes it is desirable to only attempt
    to boot from the configured devices and not from any of the default
    devices.  This patch adds support for a "HALT" item in the "bootorder"
    file - its presence will prevent SeaBIOS from attempting any default
    boot actions.
