I am back and still looking for help. I have not figured out how to get rid of the “Host Diasabled” lockup that I get after configuring my Aristocrat Variant/Veridian machine running MK7 software. After reading someone else’s post about getting this error on their mk6 machine, I am thinking maybe I have not cleared the RAM properly. I replaced the internal batteries recently. Then I ran the setchip and game software. Prior to setting jurisdiction, etc. it has me clear the sram. Is that different from the regular Ram clear that needs to occur? If so, can someone describe the process of clearing the RAM on an aristocrat variant/Veridian running mk7 software? Thanks!
