[ About the software ]

The NEC Express5800/iR120a-1E System BIOS Update Module supports the following 
functional enhancement in the NEC Express5800/iR120a-1E models:

  - Updated critical microcode for Intel(R) Xeon(R) Processor 5500 series
  - Fixing the issue that some cores of the CPU infrequently behave uncached
    access when booting the Linux operating system, which causes high CPU
    utilization.

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 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 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.
  
  * This software does not support a virtualized environment such as hyper 
    visor, guest OS, etc. Please update either on the OS which this software 
    supports or with the method of offline update.
  
  * 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 a virtualized environment such as hyper 
    visor, guest OS, etc. Please update either on the OS which this software 
    supports or with the method of offline update.
