Hmm thats not how I read the code. My system has a standard IDE device
as part of the chipset, and then also has a fasttrack controller. The
fasttrack controller comes in 2nd, (hence making it the 2nd controller
and making it marked disabled). I think your right about the 3rd/4th
controller though, what happens to those !
