Inspiron 6000, fitted with bluetooth module from Inspiron 6400.  Bluetooth ran fine before a recent replacement of HDD.  After reinstall, upgraded to XP SP3.  Subsequently found that R112482 driver downloaded from Dell site doesn't work - "could not find a compatible bluetooth chip on your system".  No alternative on the driver disk.  Comes up every time I start up laptop, inviting me to install the driver.  Where do I get one?
