I have a read quick question about a bally cinevision machine mpu board.
It was working fine, then one day I turned it on and it said NVRAM battery 2 low. I removed the mpu and replaced the two button 2032 lithium battery's then when I try to turn it on it just makes a solid buzzing sound from the mpu board and it won't even try to start up. If I switch the utx switch it will try to load but it gets stuck on an error- FATAL FAULT NVRAM DRIVER MOUNT FAILURE It will not ever go past this point no matter what I try to do.
Any idea of what to do?

Have you RAM CLEARED the machine since your battery Change?
-
Oh, and another thing...
If you already replaced the battery on the MPU and did a RAM CLEAR and still has this problem, then you need to replace the battery on the backplane.

Yes i replaced all 3 batteries, and did a ram clear. as soon as I turn power on to the MPU it starts buzzing and wont even try to start unless I move the UTX switchback and forth, then it hangs on the fatal fault screen. I also removed the bios chip, and even put another bios chip of the same # and still the same problem. One last thing I also tried is using a good MPU power supply, still starts buzzing immediately when power is applied.
All I did is just remove the two batteries and replace them with good ones (I checked) and everything went to crap!!!
Still any ideas??

I'm not sure the fatal fault problem you're having but the buzzing is a tricky problem our board repair engineer solved. Certain parts of the board are supposed to boot in sequence and as the board gets older this timing gets messed up. We put a physical 1 second delay on this out of sequence circuit of the board and it solves the problem. It is a pain to take the board all apart and apply this fix though. Flipping the atx power does the same thing. It's just annoying to have to do it every time you boot up.

Sorry for my slow reply, the problem you are explaning sounds like the problem I am having. After I NVRAM cleared the machine and figured out the progressive amount problem, the only way I can get the machine to power up is to mess with the ATX switch. It just seems weird that all I did is replace the batteries and it started messing up. I guess for now I will have to keep switching the ATX switch back and forth to start the machine.
Thank you ALL who have helped, Sean

This is an old post, but I figured some will read this.....
You can solve the "buzzing" by installing a AVBPROD0R807-00ST U16 BIOS chip. Boot the Engine with a 317 CLEAR card and Clear. Then Boot the Engine with a 317-2 OS card (the game doesn't matter), and you'll now notice the Engine doesn't "buzz" anymore. And you no longer have to toggle the ATX switch to boot the game.
The OS Updates (from 336-05, 336-09, 336-11) never updated the sequence because it was being "held" non-volatile by the batteries. Since casinos leave their machines on 24/7, batteries drying during normal machine life span, and OS updates, wasn't an issue.
Hope this helps!
