I have the same problem with promise fastrack sata 378.
I think the reason of that problem is that there are 2 version of drivers for 378.
One is when u have set the controler as raid and the othe when is set as ata (ide).
So driverpack include only the first driver (fastrack raid 378).
The second driver can be found at page of asus.com

But i hope to help.
