If the controller only has access to 2 ports, does it matter which I set the nonexistent port values to in the map?

NA is used for unimplemented ports of a valid configuration while RV is used to mark invalid MAP value. So, NA should be mixed with P[0-3] while RV can't be mixed with any other values. -- tejun - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

If that is the case, then I assume my only choice, for the 2 port controller (physically ports 5 & 6) would be [P0 NA P1 NA]. Thanks!
