This is only slightly connected with NetBSD, but I am not sure who else 
to ask.

I have a sun 4/330 running netbsd just fine. However, there seems to be 
something wrong with the eeprom memory. After each power-cycle the 
machine forgets everything entered through the eeprom(8) command, and the 
eeprom checksum is wrong, forcing me to boot in diagnostics mode over a 
serial channel every time.

This sounds like the common "too old battery" problem that sun3 and sun4 
suffers from. THe peculiar thing is that it remembers its ethernet 
address. Is the ethernet address not stored in the eeprom in the 4/330 as 
it is in other sun4:s?

Lastly, can I replace the eeprom with a working one from a SS1 or a 
sun3/80 after reprogramming them to contain the same code? We have 
several SS1:s and 3/80:s which are not being used.
