You can also go back to a previous Bios with no issues on the R13 so don't worry. I've tried them all more than once and never had an issue 
Following the update of the last BIOS 1.3.1, 1.3.1 at the restart I had the following information that you will see on the photo that I put in attachment. With the old BIOS 1.2.1 I had no problem though. Do you think I should go back to the previous version of BIOS? I have not changed anything in my original configuration, the memory is still the one provided by Dell during the manufacture of my Alienware, but it indicates a problem, hence my question. Thank you for your answers. Happy 4th of July! BIOS 1.2.1 = [IMAGE]   BIOS 1.3.1 = [IMAGE]bios message after update
Aurora R13, BIOS 1.3.1 update
