Gentlemen, I am trying to update the BIOS from A11 to A14 as I want to install Windows 7x64 under UEFI and in a related post, Dr. Yip said that the 390 was a bit 'flaky' with earlier Bios so to make sure to update to A14. I installed Win7 in legacy BIOS to run the only Bios update I see on the downloads page for this model and have downloaded it twice and run it several times. The installation always fails after reboot with the the installation progress box at zero %. Several other poster's in another thread had the same issue, with one guy saying that none of the 40 390's in his office would take the update. Unless there's something I'm missing, it looks like I'll be forced to keep the A11 BIOS for my UEFI installation. Does the fact that I have not activated the Windows installation I'm using to run the BIOS update have anything to do with it? It's status is still just as a trial installation, not 'Genuine' as it would be after activation. Any thoughts from those more well-versed in such matters? Thank you for your kind attention! Grant

A14 requires clean install of windows that does not have malware or other issues. A clean install of XP or 7 with CHIPSET Drivers and INTEL Manangement Engine is required. Antivirus Software must NOT BE INSTALLED and the Bios update program MUST BE RUN AS Adminstrator. Being at A00 and other early versions will require you to install in steps to get to likely at least A08 before going to A14.DescriptionVersionSupported OSDownloadDell OptiPlex 390 System BIOSThis package contains the BIOS update for Dell OptiPlex 390 that runs Windows and DOS operating systems.

The A14 might not apply to your configuration. See the full details of the update on the download page.The activation of windows has nothing to do with the bios. Bios is not related to the OS. A11 is the most recent update for your old model. There is no 12 or 13 bios.
