Selecting boot EEPROM
Hi,
What I want to do is have two boot EEPROMs to choose from. I want to be able to have a first EEPROM installed, but be able to boot to a second one when it is inserted in a chip socket without removing the first. Of course, I also want to be able to program the first one when the second one isn't inserted, and program the second one when it is installed. How can I do this?

Sure, you could get a little more complicated and install a small push-button under the second socket to do this. There is no easy way to sense device current to electronically switch the device as it's quiescent current is very low.
