Has anyone found out the in's and out's for working round the options on a A2100 controlled VMC ? We have several A500's and would like to re-master the hard disks so that they are all running exactly the same software, some are 6,000 or 8,000 rpm, some have T Coolant. But as the NC CPU has a coded chip its preventing us doing so as it comes up with various option alarms. Cincinati want to charge me for new hard disks rather than sell me a mastering disk. We have sucsesfully copied the hardisk in one machine and ran the new hardisk in the machine that the hard disk was copied from, but that about it. Its not that we havn't purchased the options already. Any pointers would be helpful !
