I am not loading the bootloader as I am migrating a couple of projects to permanent homes on Chibiduino boards and don't need it. So it sounds like I will need to manually set the clock fuses. Are there anything other fuse bits I should be concerned with like prescalers? I have already burned a couple of chips which have worked with simple sketches, but I didn't do any in-depth study to investigate whether their timing was accurate or not.
