I found the setting SATA MODE was set to RAID. changed it to IDE still no good..
When set to RAID, the SATA controller enables both its RAID and AHCI functions. You will be allowed to access the RAID setup utility at boot time.
When set to IDE, the SATA controller disables its RAID and AHCI functions and runs in the IDE emulation mode. You won't have access to the RAID setup utility.
