Hello,

Your vendor has locked down your BIOS through the Intel chipset.  Intel 
has not released documentation on how to disable this protection or 
otherwise update these locked/read-only regions.  However, some recent 
patches from David Hendricks at Google work around this by simply 
ignoring writes and reads to sections which would result in errors. 
This is very new code, and the result of only updating part of your BIOS 
is not guaranteed to be sane or even bootable.  If you would like to try 
nonetheless with these risks fully understood, please examine the 
patches here and let us know how they work for you:
http://patchwork.coreboot.org/patch/3471/

Otherwise it is recommended to use the vendor BIOS update utility.

Thanks,

Josh
