Attention:
  - To prevent a system failure, please read this document carefully and follow 
    the procedure for successful update.  Should your system malfunctions or is 
    powered off due to an unplanned event during update (for example, power 
    blackout or cutoff, lightening, and noise), the system may be damaged and 
    fails to operate normally.  In this case, any remedial measures shall be 
    taken at your expense.
  
  - If Windows(R) BitLocker(TM) is enabled on your system, please disable it 
    temporarily during BIOS update. If you don't turn it off, you may need 
    "recovery password" after BIOS update.
  
  - To update Windows Server(R) 2008 R2.
    Please install OS after surely updating BIOS (a version 2C12 or future 
    version) which is supporting "Windows Server(R) 2008 R2". 
  
  - Please do not select ACPI C2 by the Processor C3 Report menu when you use
    Hyper-V Ver.1.0 of Windows Server(R) 2008. When ACPI C2 is selected, 
    the display on guest VMs at the system time might be remarkably delayed. 
  
  - Please do not select ACPI C2 by the Processor C3 Report menu when you use
    Dialogic(R) Host Media Processing Softwere Release 3.0 for Windows.
