Dear all,

I'm trying to upgrade our Precision 690 from Windows Xp to Windows Vista Enterprise.

I use our SMS Image of Vista and all is almost ok

I installed manually audio drivers and TPM drivers (I have found only for Windows 2000 / XP (!!) and downloaded from http://tinyurl.com/ywtfwv)

 

My big problem is that Bitlocker cannot recognize TPM (TPM not found!)

TPM is enable in BIOS (I have verified).

Bios version is A08

 

I have found some old posts in this forum for this problem but no-solution. Any news... I have skip some step?

 

Any suggestions ?
