Does my driver have to be numbered as one of those slots? For instance, I am opening the driver from an INIT and the driver will continue to run in the background while the machine is running. Am i going to have to look thru the system file at boot time to see if there is an empty slot, renumber my driver and then open it? I read the device manager stuff but am still confused on this point. My guess is that the refNum passed by OpenDriver() will give me the slot i am in. Is this correct? Thanx, Michael
