I have a Tracer Summit running on ver 11 with an older IBM P2 computer. It has ISA slot arcnet. I'm in the process of upgrading front end to an IBM P4 and of course it does not have ISA slots. I have purchased a PCI arcnet from card from Contemporary Controls. Contemporary Controls tell me that I need to install drivers from the Summit Software. How ever XP Pro has not located them and the files that Contemporary Controls says will work "CCSI_ARCNET.INF" and "COM20020.SYS" are not on the Tracer Summit V11 software. Any help on these drivers or other drivers that will work with Tracer Summit V11 and XP Pro would be Appreciated.
