We are still in the process of documenting the Firebolt installation procedure at present.
Please accept our apologies for the delay.
Basically, you create the CD key as directed in the SB2 USB key documentation, then substitute the following commands:
instead of running: download_strongbolt2_iso
Run this command: download_firebolt_iso
This will download you the Firebolt installation image.
The rest of the SB2 instructions are the same.
We hope to have it all online soon.
