This release provides updated System BIOS(4.6.8A25) for the following 
enhancements of NEC Express5800/T120b-E, NEC Express5800/T120b-M, NEC 
Express5800/GT120b.

  - Updated critical microcode for Intel(R)Xeon(R) Processor 5600/5500 series

Attention:
  * Incorrect update could result in the problems such as failure to boot the 
    system. Update the system following the instructions in this document to 
    prevent the error in operation. Unexpected accidents such as power failure, 
    lightning strike, interrupt and noise during the system update may damage 
    the device or make the system malfunction in the worst case. Be noted that 
    you may need to pay for the repair fee for the above cases.
  
  * When Windows(R) BitLocker(TM) function is set to "Enabled", update the

    BIOS without making the function "Disabled", you may need the recovery 
    password when you boot the system.
  
  * When you use Hyper-V Ver.1.0 of Windows Server(R) 2008, do not select "ACPI 
    C2" in the Processor C3 Report selection menu in the SETUP menu. If you 
    select "ACPI C2", it could result in much-delay of the system time display 
    on the Guest OS.
