Comment (by hailfinger):
Two possible reasons:
* Differing LPC bus frequency.[[BR]]
* Differing GPIO configuration, which may result in uninitialized #WP
and/or #WE on the flash chip.
You may want to verify both settings with an oscilloscope or any other
tool you have handy. In case you want to verify correct settings from the
software side, you have to make sure BIOS shadowing is disabled, then run
a few timing trials of flash readout both under LB and proprietary. The
speed should not differ. For GPIO configuration, check superiotool output
differences and MCP55 GPIO registers (the latter may require a NDA to get
a map of meanings).
