I was just about to install them too!
So, browsing around, noticed that somebody said that the 2.41 and 2.42 nForce 2 drivers were removed from the NVIDIA site. And yes, they were. In their place are the 2.03 drivers and a little note:
Updated May 23, 2003: If you have previously downloaded the 2.41 or 2.42 nForce kits and have experienced any problems please follow these instructions on how to re-install previous drivers.
So maybe more was wrong than just the IDE driver. Just a word of warning, folks.
