Jonathan D We are trying this out in a modern.ie virtual machine, specifically, the windows 7 IE 11 vm (which is 32-bit). Make sure to enable 2D video acceleration or openFrameworks apps will be scared because they can't find a framebuffer they like.
 
Sean M Getting the D-Imager up with the BeagleBone
How to setup the BeagleBone to work with the D-Imager:
  1. Download the D-Imager BeagleBone image BeagleBone
  1. Copy the image onto the MicroSD card
  1. I did this by following Adafruit instructions
  1. Remember that if you do dd in OS X, you can do kill -INFO 12345 on the pid to see the transfer status :)
  1. Oh actually CTRL-T in the dd process window also works!
  1. Not entirely sure of what worked to get a serial connection to the BeagleBone, but I did the following:
  1. Downloaded the drivers from here 
  1. Followed the instructions from here (but not using their Info.plist)
  1. Rebooted my computer, then unplugged and replugged my BeagleBone
  1. Then I could find the /dev/tty.usbserial-*B device, which is the BeagleBone
  1. sudo screen /dev/tty.usbserial-*B 115200, then use user root (no password)
  1. Download the code and drivers
  1. asdf
  1. Install a toolchain to cross-compile the drivers for the D-Imager
