The method I have used before when installing on "impossible hardware" has been to remove the harddisk, the Compact flash, or what it might be, and than installed an image or how the software might be, while the memry unit is installed in another PC. Then after the software/operating system has been installed, the unit is transfered over to its original hardware, and booting have used to work ok. I have not tested this procedure for a headless system. Just an idea.
