Where is the NVRAM located on a 4500M, and how can I change it? Also, the
lithium battery? Any other suggestions for resurecting this router? Here
is what's happening and what I've tried:

For the past serveral days, I've had to power up my 4500M a couple times to
get it to boot; today it won't boot at all. It gets just this far and
hangs:

System Bootstrap, Version 5.3(16) [richardd 16], RELEASE SOFTWARE (fc1)

I've swapped DRAM, Shared RAM, FLASH, and BOOTHELPER FLASH with my 4700M and
all work fine in the 4700M. I have not swapped boot proms, but that
shouldn't matter since FLASH seems okay.

I've swapped all interface modules and all work fine in the 4700M. I've
tried booting without any interface modules; no luck. The 4500M fans power
up, and so do the LCDs on the interfaces; seems like the power is okay.
