Hi guys,

 

My Sun Ultra 30 NVRAM battery is dead and I purchased a  M48T58Y-70PC1 from Mouser. I’ve tried reprogramming and it seems to accept the commands no issues but when I restart the machine I get “Incorrect configuration checksum. Solaria 7 then freezes when I boot to disk.  I’ve tried the original NVRAM with these commands and it works fine. System boots no issues. Any ideas?
