The system firmware + Embedded Controller firmware lives in a 1Meg SPI 
NOR flash part connected to the EC.  The 1Gig NAND flash part does not 
store any system firmware.

I prefer to use the term system firmware because BIOS refers to a legacy 
product class.  OpenFirmware's capabilities are so far above a legacy 
BIOS product you can't even put them on the same scale.
