Group: Hardware/research/anti-freedom/Intel Management Engine/HP Elitebook 2570p
This laptop cannot even boot without nonfree software.
However doing tests on it to understand better the Management Engine and the laptop lack of freedom is still interesting.
As for now:
- That laptop requires a signed and nonfree Management Engine firmware.
- It also requires a nonfree Embedded Controller (EC) firmware that has to be part of the Coreboot image.
- It still needs to be tested without CPU microcode.
This laptop uses the Ivybridge microarchitecture.
|Keep ROMP + BUP ME partitions||
|FPTR, ROMP and BUP partitions were removed||
|Removed completely the ME partition like for GM45 (1, 0xffff for region 2 base)||
|Removed cpu_microcode_blob.bin from the coreboot image with cbfstool||
|Coreboot image built without the microcode||
