Looking for clarification on TPM password vs BIOS admin password. RRS feed

  • Question

  • In our environment, we set a BIOS admin password. You need to know this password to get back into the BIOS later.

    However, during MDT cloning, now that I've added Bitlocker encryption to occur during imaging, I randomly see one error
    stating that MDT failed to see the TPM password.

    What exactly is that password? Is it the same as the BIOS password? When I see this error, I simply reboot to finish MDT, then
    at the desktop I go into Bitlocker and Activate...then a key is instantly written to AD.

    This doesn't happen every time, sometimes MDT finishes with a clear white summary screen.
    I read in several places to add TpmOwnerPassword=xxxxx in the CS.INI and I guess I could, I just don't know if that is what
    the BIOS admin password is. We never set up any other password in BIOS other than the supervisor password.

    Any clarification of Supervisor (admin) BIOS password vs TPM password would be greatly appreciated.
