+BIOS Sledgehammer is able to handle the special case of the 6.41.x firmware. This firmware comes in two different versions:
 
  * 6.41.**197** is used for devices that have a TPM 1.2 by default
  * 6.41.**198** is used for devices that were downgraded from TPM 2.0 to TPM 1.2
 
-The problem is that the [Win32_TPM](https://msdn.microsoft.com/en-us/library/windows/desktop/aa376484(v=vs.85).aspx) CIM class does not provide the BUILD part in the ``ManufacturerVersion`` field. Therefore, it can not be detected which 6.41 firmware is currently active.

-To support this, BIOS Sledgehammer can change BIOS Settings just before the TPM update using the file `` TPM-BIOS-Settings.txt``, so these two BIOS settings will be turned off. If no TPM update is required, this file is ignored. It works exactly the same as described in [BIOS Settings](#biossettings) and should only contain the changes that are required for the TPM update to succeed.

-**NOTE:** It is perfectly fine to set a setting here differently than in [BIOS Settings](#biossettings). For example, in this file **Trusted Execution Technology (TXT)** can be configured to *DISABLE* here (as this is required to allow an TPM update) but *ENABLE* in [BIOS Settings](#biossettings). The later is executed after the TPM update so the settings there will be in effect.

-### Disable BitLocker check
+### Disable automatic BitLocker decryption
 
-In cases of updates for in-use machines, the automatic decryption of BitLocker might not be desired as it will require a full roll-in of BitLocker. For these cases, it is possible to remove the TPM protector from BitLocker and disable it before BIOS Sledgehammer is run and then specify **IgnoreBitLocker==Yes** in ``TPM-Update.txt``. When set, no automatic decryption will take place.

+In cases of updates for in-use machines, the automatic decryption of BitLocker that BIOS Sledgehammer performs might not be desired as this will require a full roll-in of BitLocker later on. 
+
+It is possible that a script (executed before BIOS Sledgehammer) removes the TPM protector and then pauses BitLocker protection. Adding the parameter **IgnoreBitLocker==Yes** in ``TPM-Update.txt`` will cause BIOS Sledgehammer to ignore BitLocker all together and not start a full decryption.

 # Ignore BitLocker - If activated, no automatic BitLocker decryption will take place
 IgnoreBitLocker==Yes

When removing the TPM protector using ``manager-bde.exe`` and forget to also specify the **RebootCount** parameter, you can lock yourself out of your device.
