Another thing is something that a friend of mine says yesterday: why instead of removing the chip, take and desolder only the vcc pin, put a micro-switch on it, solder another chip on top of the existing and do the same with its vcc pin, so with two micro-switches you can select wich bios chip use. What do you think about this solution?.
You also need to do this for CE and CS.
Actually not, there are no CE or CS signals here.
But don't use Vcc, use INIT# instead.
We just need to learn how it looks during boot and how it is connected on the two chips, then the U10 pads can be used to fit a socket and T1/T2 pads used for the switching circuitry.
No idea how hard or easy it is to desolder single pins instead of the complete chip. It is a good idea though!
Too hard, better just use the ready made PLCC pads for a socket. :)
