The embedded controller (EC) in these machines often interacts badly with flashing, either by blocking all read/write access to the flash chip or by crashing (it may power off the machine or mess with the battery or cause system instability).

			We support LPC/FWH flash on most recent Nvidia chipsets (ION is untested/unsupported so far). However, we can't support SPI flash on Nvidia chipsets (except SPI behind LPC/SPI translation) because we don't have the necessary docs for the SPI interface. There are three ways to solve the problem:
