My new project - multiple sections on larger SD cards. It makes possible to use more than just 7 GB (TOS 1.04 and higher) of card's capacity.

It needs new drivers, new autoboot installer program and SW capable to write disk image to any loc. of SD card, not only at beginning (as does all Win. SW I saw). I updated my Drive Imager for that:
