Topic: chumby One ROM image
If you're hacking around on your chumby One and manage to accidentally overwrite the bootloader, or if you want to upgrade to a bigger SD card, you can now go grab a zipped copy of ROM 1.0.3, unzip it, and then write the resulting image out to an SD card.
Windows users can use win32imagewriter. Linux users should make sure the drive is unmounted, then dd the unzipped rom to /dev/sdX (where X is the letter of the USB reader). OS X users should make sure the drive is unmounted (not ejected) and dd the image to /dev/diskN (where N is the number of the drive).
When you boot off of a freshly-formatted SD card, it will repartition itself such that partition 6 (eventually formatted as /mnt/storage/) fills up the remainder of the card, so you'll notice it reboot once on its own. Also, since it'll need to reformat /mnt/storage/, it will take a long time on the screen with the colored circles (possibly several minutes), so just leave it on that screen.
I'd be curious to know if anyone finds this useful.
