I am sorry for the issue.
In order to use Intel® Smart Response Technology the SATA controller mode must be set to RAID in BIOS. This is probably the reason why it is not possible to enter the RAID option rom. Please bear in mind that changing this option from AHCI or IDE will require reinstallation of the operating system.
Once you do this, the acceleration option should be available in the Intel® Rapid Storage Technology software. If it is still not showing up then it is probably related to the data on the drive, such as a previously existent RAID structure.
