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!
