Hi Tom. Thanks for writing.

Yes, that code is still necessary. There's a new aic7xxx driver by Justin Gibbs at Adaptec which is now being beta tested which corrects this issue. Something to note, however: the media transfer rate for those disks is at most ~20MB/sec. Therefore, you only exceed the 80MB/sec bus speed if you have more than 4 disks all doing maximum I/O at the same time. Since the PowerApp.web 100 has at most 2 disks internally, you really shouldn't see any significant performance difference.
Hope this helps. Thanks for buying Dell! Matt Domsch Dell Linux Systems Group Linux OS Development
