The other option would be putting inside 2 flash chips, and an external switch to enable one or the other.
The System Reports a SST 49LF004A , while it is really a SST 49LF004B (4mbit / 512KB).
Ok. If there is physical room for another chip inside the machine you can just connect all important signals across (maybe 10 or so), build a simple transistor switching circuit for the chip select line and finally run only three wires out of the machine. They can be as long as you like.
Flashrom was unable to write on it. So my tests were done using my external programmer. ( the netbook saved the day :) )
So how would you reprogram the flash chip inside the machine? Running wires from the flash chip out of the machine will probably not work.
