It says it has coreboot pre installed. I assume therefore its not difficult to flash Heads, which is based on coreboot?
Honestly, I don’t know if that’s the case; I always got scared whenever I saw the prerequisites for Heads in combination with the strict list of supported hardware. FWIW, the NV41 that’s used for enabling Heads on NovaCustom’s device is included in the short list of supported hardware for Heads, while -unfortunately- the same doesn’t apply to the StarBook. I would love to be proven wrong though!
