| Jun 19, 2017 at 17:36 | comment | added | Melab | @northox "Typically"? Signature verification of the BIOS by the hardware on personal computers is a rather recent feature. | |
| Apr 24, 2017 at 21:19 | comment | added | northox | Seems like your firmware is not properly resetting the Static Root of Trust for Measurement (SRTM). Typically, this is a signed blob or a read only portion of your firmware. I suggest you check your BIOS options and/or your BIOS as a problem and should be updated. | |

| Mar 3, 2017 at 11:52 | comment | added | André Borie | Does your embedded board come with any documentation about this? It could be a configurable option in the firmware. | |
| Mar 3, 2017 at 11:20 | comment | added | Pritha Ganguly | I had also extended PCR-16. When the hardware lost power, PCR-16 got reseted to all zeros but PCR 0-15 did not. | |
| Mar 3, 2017 at 10:10 | comment | added | André Borie | Do the PCRs get cleared when the hardware looses power? | |
