Have Feather and tried to get it booting. It does seem to fit on my "64" meg device (which seems to suffer from the same marketing hype HD makers use and Windows reports as 62.0 megs of space).

It does not boot though. They seem to know this happens, as the feather website also says "If this doesn't work, try downloading the Debian “mbr” package and using that to install an MBR on the USB drive". Unfortunately, I don't have a Linux running that I can install packages into. Am I out of luck? Is there another way to make this thing bootable?
