The above note is sadly not a joke.

Not so, it works very well on a whole bunch of them.

Some info Carl-Daniel didn't post, maybe it is informative;

It seems that the system has a Winbond W25B40 or W25B40A flash chip.
This is an SPI flash chip, but it seems to behave just like a FWH
type chip.

While waiting for Carl-Daniel you can try the attached patch. I doubt
it will work but you never know.
