[rescue] Ultra 2 NVRAM - failed fix

[silcreval]

Hi Jon - it looks like it is OBP 3 on this machine so the MKP prompt appeared to work. If I reset (rather than power down) the mac values are displayed in the title screen. It's just power off where everything is lost.

Hi Ethan - the chip appears to work in situ, but doesn't save its settings. I tried the watch-clock command and that worked as expected (the second timer showing)

Hi Peter - you mentioned a M48T58 - although this is definitely fitted with a M48T59. I wonder if the chip has been replaced previously with the wrong type? I've ordered a new M48T58 so will see if that works.

Thanks for the help all, much appreciated.

- Ian
