[rescue] Ultra 30

[Rob Craig]

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? 

01 0 mkp
80 1 mkp 
08 2 mkp
0 3 mkp
20 4 mkp
c0 5 mkp 
ff 6 mkp
ee 7 mkp
0 8 mkp
0 9 mkp
0 a mkp
0 b mkp
c0 c mkp
ff d mkp
ee e mkp
0 f 0 do i idprom@ xor loop f mkp
