What kind of performance issues are you having? Sil (used to be CMD) hardly has a history of making good controllers. Rather on the contrary. Preempt tends to try and improve latancy for user applications at the expense of the kernel and drivers, so not likely to improve things for the sata controller, in fact more likely to give it even worse performance. -- Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
