Just wondering if I should expect anything on the serial port or on the
monitor if my AlphaStation has an NVRAM self test failure. Anyone know?

I still need to identify the NVRAM chip(s), although replacing them means
learning how to desolder and resolder surface mount stuff, which I have
never done before.
