I just replaced both my nvram batteries in the cpu when I got nvram battery 1 and 2 low message. Rebooted machine with install card and game card inserted. It booted to install screen, but nothing showed up. That is happened before, so I just restarted. This time got an error message asking for complete system factory reset - said something about system not partitioned - wish I had taken a photo. Anyway, thought it might need a ram clear,mason ran the ram clear card. Tried to do install card and game card again, but now it keeps giving me error messages on black screens with either “no hard drive detected†or “ boot device other than first compact flash or diskâ€. Any advice or suggestions would be appreciated. Thanks!
