I love updating the BIOS on hardware devices. I just put the latest version 1.0.5 on my new Canon EOS 5D. It’s actually a fairly easy process – much easier than flashing the BIOS on, say, a computer. I simply take the card out, put the new BIOS image in the root, put it back in the camera, select the “update” option, and BAM. Less dangerous than doing that to a PC… and not all my machines have floppy drives anymore to do that with! Flashing the camera also retained all of my customizations, whereas flashing a computer would wipe out any system level configurations which would then need to be reset. Fun!
