When I power on my 6500/SUP720, it says :

After issueing the 'confreg 0x2102' command and then the 'boot' command all goes well. The Sup720 correctly boots up. I can configure it and reload it (by reload command). But when powering off/on, nvram is corrupted again.
I found the FN27595 (CSCec34824) and it seems my board is impacted (serial number + hardware revision).
The solution is not clearly explained : do I really have to change the entire SUP720 ? What if the SUP720 is not maintained anymore (bought in 2003)?
Do I have to buy a brand new one ?
Can it be repaired ?
I saw in another post that replacing the on boad battery had solved a similar problem ...
Somebody help me please ?
