BarryAllen Guide:
First of all we have to do fat or ext fat format of good read/write USB flash and can accept linux partions
After usb flash attached we download latest barry allen release Barry allen latest versions (TSPANEL will do tha job)

We open barry allen from plugin browser

first copy your image with extension nfi to /mb_images by software dcc or any ftp program

barry allen opens special folder in dreambox media/ba/ba/ contains all installed images

Booting from external flash image
There are two ways to boot from exteranl flash image either from Barry allen menu
select installed image for booting -then we select the image for booting
or reboot your dreambox and from the barry allen menu which appear early in reboot we select the image

Control of multiboot images
you can install,delete installed image,backup installed image and show information about images from the barry allen menu

Note: when rename multiboot image better to keep the name short and less than 40 characters and no spaces
