It does ID your chipset but it seems the flash chip is write
protected with some unknown GPIO, which makes it impossible to
identify or write the flash chip from software.

You could perhaps identify the flash chip by visual inspection but
that won't allow us to write it anyway. :\

I would really like to set up a sandbox for proprietary flashers so
that we can easily learn what they are doing.

None, unfortunately.

Unless the BIOS chip is socketed and you have a way of flashing the
chip outside of the system. (Using another, supported, mainboard e.g.)
