I've updated the v5.0x installation instructions to provide more details for the senerio where a user runs the CNC12 installer without having the Acorn board powered up and connected to the CNC PC. This is a pitfall if you don't follow the instructions (to have the Acorn powered up and running before running the CNC12 installer). For CNC12 v5.1 we will make changes to the CNC12 installer so this is more fool proof. for now the documentation covers it for those that read it

fyi.. the Centroid CNC PC Tuner is a bit smarter than the v5.08 installer and does not present this trap if you don't have the Acorn board connected to the CNCPC.
