your best bet is to see if the board manufacturer is prepared to share the tools to allow you to inject the image into the BIOS/Firmware of the base board - Fujitsu is good for this.
but most manufacturers prefer you to send the image and they will prepare a flash updater for you, some charge, some do it free.
good luck
