You can (and you have) disabled the promise fastrak controller. This is only for raid on the Pata drives & the second two SATA drives.
The First two SATA drives are controlled by the Intel Raid.
So disabling the promise controller will not affect your machine unless you had Pata/second sata port Raid.
