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?.
Having a chip on your LPC bus with data and address lines connected but with no Vcc will mostly likely screw you. Operation of the chip will be undefined.
You also need to do this for CE and CS.
No idea how hard or easy it is to desolder single pins instead of the complete chip. It is a good idea though!
On PLCC it will be pretty hard since they are not really pins that you can just lift up off the pad.
