Actually, on many older drives from that era, the C/H/S parameters are not on the drive, and the auto-detection idea was in it's infancy. So get the model number off the drive, and go to the manufacturer's website to find those parameters.
Another way, is to plug the drive in question into a modern machine, do an auto detection, and write down the numbers if it detects it.
Lastly, is that battery a 4.5 volt?
Some older boards came with a 7.2 volt originally, so your battery at 4.12 may not be enough to hold the CMOS if this is the case. A fully charged 4.5 volt usually works on one of these though.
Best of luck with your dinosaur Galvo!
