[1] OPF Members Only, CDA Restricted
|
|
[2] Hardware capable, software still under development
|
|
[3] Lack of open firmware makes owner-controlled trusted boot unavailable
|
|
[4] Multiple closed binary files are required to boot. At least one of them (the ME) is signed by Intel and can never be replaced with a libre alternative.
|
|
[5] We are aware that at least some community members have access to the schematics. Provenance is unknown at this time.
|
|
[6] An attempt is currently being made to activate the IOMMU without blobs. It is still unknown if this is possible on this particular hardware.
