This bzip2-compressed SMC disk image was created from a "stock" LRI SMC 
RegulusOS microSD card (obtained from Chris Wahl, 3/28/2017). 
Image was created in the following steps:

1. Attach Kingston FCR-HS219/1 card reader/writer to Ubuntu USB port
2. Insert microSD card into Kingston. 
3. Execute 'sudo lshw', look for microSD card device, e.g. /dev/sde
4. Extract and compress image:

  sudo dd if=/dev/sde bs=64K conv=noerror,sync | bzip2 > mySMCimage.img.bzip2

To install the image onto a new card:
1. Insert a card into the Kingston - ANY DATA ON THIS CARD WILL BE OVERWRITTEN
2. Run a sh with sudo: 'sudo sh'
3. Execute 

   bzcat mybackupfile.img.bzip2 | dd of=/dev/sde bs=4M

   (this operation takes about 55 minutes)
