Intel Atom Processor C2000 Product Family B0 setp has a bug. AVR58(System May Experience Inability to Boot or May Cease Operation), which can be find in Document Number: 520653, Revision: 2.9. For C2758 B0 step, does the microcode and bios need to be updated(Upgrade from M01406D8128 to M01406D812A )? Is there any risk if it is not updated? How about C0 step? Thanks!
