In my Dell BIOS, there is a setting Advanced Chipset Features > 
Integrated Peripherals > SATA Mode.  Initially, this was set to ATA.  
Change it to RAID.  This enables AHCI which enables the faster SATA mode 
drivers.  Note, setting RAID mode in BIOS will NOT implement RAID, just 
the AHCI drivers.  Certainly, Dell's initial ATA setting was to lower 
support calls.

However, proceeding with a Ctrl-I at boot, WILL take you into Intel's 
Rapid Storage Technology option ROM that will reformat.
