ECC RAM is a nice to have thing and or but for a 24/7 running device it
makes sense. The TPM module I am using in the PC Engines APU6B4
I was able to buy one from Dasharo, I was soldering a 10 Pin header
on the bard and then I connect the TPM module there, together with
the latest BIOS version (19.01) the BIOS recognizes the TPM module
but pfSense itselfs is not taking any advantage of the TPM module.
Perhaps with the next BIOS it could be something is on change at
this point.
