I am mostly testing with windows 10, and tpm.msc complains that TPM is
malfunctionning with seabios & my chhanges (even tough it does some
exchanges). With the UEFI branch, it passes, but Bitlocker still complains
the TPM is malfunctioning. Apparently, this could be related to
PhysicalPresence (I have no clear idea how PP works, I'll need to study
that a bit)
