<li>Start by using cfdisk to format the SD; it's easier than calculaing needed for sfdisk. I velieve there a version in Extras-devel, but why bother with that when there's one in Easy Debian.

<li>Use cfdisk to set up 2 partitions. I created a small one at the start of the available space to reserve the name mmcblk1p1, then a 5120MB one at the end, then deleted the one at the beginning and recreated it using all the remaining available space. Make sure you remember to write the new patritions, then quit cfdisk and unmount Easy Debian using the icon.</li> | <li>Use cfdisk to set up 2 partitions.
