We need a seabios support: commit 54ae5436df92c8caf0a814a7c653adb1d75a084c Author: Kevin O'Connor <kevin> Date: Sat Jan 12 16:36:11 2013 -0500 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.
