Right now the code for dealing with the 2842 and the 2742 is one and the same. To do what you propose would mean adding an isa probe and doing the same looping through the slots that the eisaconf code does already, although the 2842 probe would have to do it once for each card probe instead of just creating the device nodes once like the eisaconf code does. There is simply no reason to break the probe up. It only adds complexity and code. > > > Regards, > Terry Lambert > terry@lambert.org >--- >Any opinions in this posting are my own and not those of my present >or previous employers. -- Justin T.
