The only way I can think of to use it is that if either drive says UDMA > 33 then we know its 80 wire. Otherwise we can't really prove anything. And if neither drive says > 80 wire we have to go on what other info we have, which for NVidia appears to be "guess 40". I'm not sure therefore we gain anything ? - 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
