Endpoint Encryption

I work for a company that has 3 Dell Precision T7400 with the SAS 6/IR integrated workstation raid controller and i've updated the BIOS and driver for the controller, i was unable to update the firmware for the controller though. I installed the SEE 7.0.3 Full Disk Edition and rebooted, it came up fine the first time but the second reboot it came up with a error message stating "An un-supported storage controller has been detected." The drives are running in ATA mode. I've decrypted the drives and un-installed the software for now and they are up and running. I need to get this installed, does anyone have any solutions?

I am very sure that you need to try a different mode here ..... do you have AHCI ???

yes i do but i believe i did also try that too and it didn't work either

if you have already AHCI then try few other modes or may be try disabling it -- if this also doesn't help then try getting see 7.0.4 client packages from Symantec Tech support and see if this resolves the issue ....
