Your Dc_flash.bin file is corrupt. You need to find a "fixed" replacement. Just deleting the file won't solve the problem because Chankast creates the file again, and does it wrong (you'll know that he file is corrupt if the BIOS prompts you to input date/time twice). I'll also make a stab in the dark and say that the image you have isn't selfboot. If it isn't selfboot, you either need to hack the image to make it selfboot or use a bootdisc (like Utopia).
