Actually,
I downloded some of the packages from:
http://domino.io/firmware/pi/1.1/packages/base/
Then I Unzipped just the commands and copied them to my Usb FlashDisk.
This FlashDisk was then plugged into the PI and CORE Boards,
- and now I can execute the Commands (fsdisk, mke2fs, etc) without actually installing any packages.
