Boot from a 16MB SD card

Call for guest posts! I’m going to be away for ten days, and Ben and Helen will be babysitting this blog. They’re looking for guest posts from you – do you have a Pi project you think we might be interested in? Email info@raspberrypi.org with your submission, and if the team likes it, they might feature it here.

A little activity for you to try at home – if, that is, you’re able to find an SD card from the past. This one is 1000 times smaller than the one that’s in my Raspberry Pi today. I’ve no idea where I’d start looking for an SD card this small in 2014; get rummaging through your drawers and let us know if you have any luck. You’ll need a USB memory stick too, large enough to fit your operating system on, because 16MB isn’t going to cut it.

16MB SD card

Read it carefully – that says 16 MEGAbytes.

Mike Redrobe had nothing to do one afternoon, so he decided to make his Pi boot from something he’d found down the back of some prehistoric sofa. With a very minimal amount of work, he was able to put all the pre-boot files (9MB) for Raspbian on the SD card, put the boot image for Raspbian on the USB keystick, edit cmdline.txt and boot up. Read all about it on his website.

I’m not quite sure why all of us here at Pi Towers think that this is so much fun, and suspect it speaks to the fact that most of us don’t have souls or a sense of humour.
