Well, but then the thing that programs FPGA is not Linux, so this is little off-topic here. [But yes, there are systems where you want to program FPGA from bootloader, because it is easier that way, or maybe because it provides your video card.] Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
