[ About the software ]

The NEC Express5800/R120b-1, NEC Express5800/R120b-2, NEC iStorage NS500Ra, NEC 
iStorage NS500Rb System BIOS Update Module supports the following functional 
enhancement in the NEC Express5800/R120b-1, NEC Express5800/R120b-2, NEC 
iStorage NS500Ra, NEC iStorage NS500Rb models:

  - 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 
    system BIOS after making the function "Disabled". Then make the function "
    Enabled" after update and reboot of the system. If you update the system 
    BIOS without making the function "Disabled", you may need the recovery 
    password when you boot the system.
  
  * When you use Windows Server(R) 2008, be sure to refer to "Hardware 
    Compatibility Information" and "Software Compatibility Information" in 
    Windows Server(R) 2008 Information-related WEB site.
  
  * When you use Windows Server(R) 2008, be sure to refer to "Installation 
    Supplement Guide" in Windows Server(R) 2008 Information-related WEB site to 
    prevent the error in operation.
  
  * 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.
  
  * This software does not support virtualized environment. Please update 
    either on the host OS which this software supports or with the method of 
    offline update.
