Hi Marc, The bzipped file is the image of my CF card (including boot sector and mountable minix filesystem): http://king.net.pl/~newchief/elks/32MB.img.bz2 The other file is the diff of all of my changes: http://king.net.pl/~newchief/elks/my_changes.patch I must admit, I was looking into wrong places. As I mounted this image, it indeed contains MINIX filesystem with /linux file in it, and that file indeed has magic string "ELKS" at offset 0x1E6, everything that run_prog() needs. So I suspect, load_zone() does something wrong. Note that I wasn't able to boot from 360k floppy either (with the same outcome!), despite all the changes regarding 360k floppies, as in my patch.
