Introduction. Unified Extensive Firmware Interface (UEFI) is the next generation of Basic Input Output (BIOS) and was released in 2. What is Basic Input Output System (BIOS)? Basic Input Output System (BIOS) is the very basic Operating System embedded into your systems i. The BIOS setup allows you to change some of your hardware settings and to boot from installation media with a proper Operating System e. Windows 1. 0. What is Unified Extensible Firmware Interface (UEFI)? Associated with BIOS is the Unified Extensible Firmware Interface (UEFI) which is essentially a modern more advanced version of BIOS that has increased functionality and additional security. Because of the strong connection and familiarity of end users to the word BIOS this is usually denoted UEFI BIOS and not just simply called UEFI. For convenience many call a UEFI BIOS just BIOS and call an older BIOS a Legacy BIOS. Definitions and nomenclature will differ slightly from guide to guide. BIOS is used in this guide to collectively group both the UEFI BIOS and Legacy BIOS. How do I tell if my Computer has UEFI Support? This is best done by looking at system information. Press . The SMBIOS version revision will never be updated with a BIOS update. You will need to check your BIOS Setup. If it is 2. 5 you will have a Legacy BIOS. If it is 2. 4 you will have a Legacy BIOS and the processor should be checked for 6. Bit compatibility. Link para baixar o aplicativo Key Viewer. If it has an SMBIOS of 2. Windows 1. 0. The SMBIOS version has also been loosely related to the version of Windows the hardware is most likely to ship with: 2. Early Windows 8 Hardware. Late Windows 7 Hardware.
Get more out of your computer when you hook up the right power supplies. Designed for offices that rely heavily on multiple computers, a simple supply can reduce the risk of brownouts and other common problems.Early Windows 7 Hardware. Early Windows Vista Hardware/Late Windows XP Hardware. Early Windows XP Hardware. Boot Mode and Secure Boot State. For systems with Windows 8 or Later installed you will have BIOS Mode and Secure Boot State shown. These technologies should be enabled where supported by the hardware. If they aren’t Enabled you should Enable them as instructed below for maximum security and performance. This information doesn’t show if you are currently running Windows 7. For a Windows 7 install in all cases Secure Boot will be disabled (as its unsupported by Windows 7) and the UEFI Boot may also be disabled. This will be discussed in more detail later. BIOS Version. The BIOS version is the manufacturer model specific BIOS version and will be the version that is updated. OS Name and Version. Take a note of the OS Name. This will tell you what Edition of Windows 1. RS1 (1. 60. 7)1. 05. TH2 (1. 51. 1)1. 02. TH1 (1. 50. 7)If running Windows 1. Windows 1. 0 RS1. If you are still running Windows 7 or Windows 8. Windows 1. 0. You should refer to my guide Download a Windows 1. OEM and Retail . iso. If on the other hand you are on this guide looking to Exhibit OEM Downgrade Rights the OS has to be either Windows 1. Pro or Windows 8. Pro. My Product Key. Microsoft Digital Marker – Windows 8. OEM, Windows 8. 1 OEM and Windows 1. OEMFor newer hardware you will have a Genuine Microsoft Label (GML) affixed to your system. This GML changes colour with respect to viewing angle. If you have a GML you should have a Microsoft Digital Marker (MSDM) Advanced Configuration and Power Interface (ACPI) table embedded within your UEFI BIOS. This MSDM table contains a unique 2. System Locked Preinstallation (SLP) key which will automatically be input by Windows 1. Build 1. 43. 93 Installation Media during installation: Windows 1. Build 1. 43. 93 Installation Media is multi- Edition and accepts and automatically inputs all these keys. Thus it is not necessary to lookup your key. However we can use RW- Everything to dig out the additional information. Select Access and then ACPI Tables: Clicking on this MSDM should give you your unique 2. Windows 8 OEM, Windows 8. OEM or Windows 1. OEM key. Unfortunately there is no easy means of determining the Edition of Windows the SLP key is for from RWEverything which isn’t an issue as the Windows 1. Systems with Windows 8. Pro OEM, Windows 8. Pro OEM and Windows 1. Pro OEM will possess a System License Internal Code (SLIC) ACPI tab for Downgrade Rights to Windows 7 Pro OEM discussed later. Microsoft Code of Authencity – Windows XP OEM, Windows Vista OEM and Windows 7 OEMFor systems shipped with Windows XP, Windows Vista and Windows 7 a Code of Authenticity (COA) with a 2. The Product Key on the Windows 7 COA is accepted by Windows 1. Build 1. 43. 93 Installation Media (but not typically used with Windows 7 OEM Installation Media). Use your smartphone to take a picture of it before Windows 1. Installation. There was a change in print quality of the COA when Windows Vista was released which made the COA prone to fading. As a consequence for most Windows 7 systems the COA was Placed in the Battery Compartments of Laptops to Reduce the Problem of Fading. System License Internal Code (SLIC) Version – Windows XP OEM, Windows Vista OEM and Windows 7 OEM. For Windows XP OEM, Windows Vista OEM or Windows 7 OEM installation the 2. Digit Product Key on the COA is typically unused. Instead OEM System Locked Preinstallation is applied. This means that one may exhibit Downgrade Rights on systems that have no Windows 7 Pro COA or Clean Install Windows 7 OEM on systems that have faded COAs: Instead of using this unique 2. COA for installation an OEM System Locked Preinstallation (SLP) Key is input by Dell Branded Reinstallation Media. You are interested in 2 fields: In this case the OEM is Dell and the SLIC Version is 2. The example I used was from a Dell Latitude 7. Windows 8. 1 Pro. It doesn’t have a Windows 7 Pro COA but is eligible to run Windows 7 Pro using OEM Downgrade Rights. An Inspiron 7. 34. Windows 8. 1 (Home) and hence doesn’t have any OEM downgrade rights. It has no SLIC tab and hence Windows 7 cannot be activated by use of OEM SLP. Systems sold with Windows Vista OEM in the period of 6 months before the release of Windows 7 may have an SMBIOS of 2. SLIC version of 2. The latest BIOS update won’t change the SMBIOS which will remain at 2. SLIC version to 2. This is because Windows 7 was a free upgrade for such systems (e. Opti. Plex 7. 60 and 7. Opti. Plex 7. 55). Note RWEverything doesn’t state the Edition of Windows 7 to be installed. In testing the SLIC seems not to be Edition specific. To be licensed correctly you should match the Edition on the Windows Vista/Windows 7 COA. Note for the Free Windows 1. Upgrade Microsoft will verify the SLP key and SLIC of the BIOS are eligible for Windows 7 OEM and if they are give the green light for Product Activation. The system profile of the motherboard will then be stored with a Microsoft Product Activation Server during the initial Upgrade Installation (essentially the series of numbers you see in the RW- Everything). An Initial Clean Installation will only work with the unique 2. COA. The SLP key cannot be manually input for an Initial Free Windows 1. Clean Install however a Genuine. Ticket can be generated on the Windows 7 OEM SLP install and used to Initially Activate a Windows 1. OEM Install without a Product Key. Downloading the Latest UEFI BIOS Version. You have the System Manufacturer, System Model and BIOS Version/Date. You should compare this with the version offered by your Computer Manufacturer e. Dell, HP and Lenovo. This guide is Dell based so I will use a Dell system as an example. For Dell systems I prefer the use of Downloads. Dell. com opposed to Product Support Page. The Product Support is supposed to list drivers and downloads specific for your Service Tag making life easier. Most UEFI BIOS update are cumulative hence if you are upgrading from A0. In some cases however the latest UEFI BIOS requires an older version to be present first and in such cases you should attempt to take the smallest number of steps to get to the latest version. The attempted update from A0. A1. 8 in an Opti. Plex 7. 90 for example states that “You must upgrade to A0. BIOS”. If I go to support. Dell. com I won’t get all the versions, notably the important version A0. On Downloads. Dell. I get all the versions: I will use my Opti. Plex 7. 01. 0 as an example. Get the latest update from Downloads. Dells. com is pretty simplistic: Updating the UEFI BIOSBecause the UEFI BIOS is a firmware update*, it needs to be applied with slightly more care than a standard driver install.* A Firmware update is applied to the hardware directly. A Driver Update is applied on top of a Windows Operating System. This means Firmware updates will remain intact once an Operating System is reinstalled and Driver Updates will need to be reapplied. Ensure All Programs are closed before Updating the UEFI BIOS. If using a Laptop ensure the AC adaptor is plugged in and that you have at least 5. DO NOT POWER DOWN YOUR SYSTEM IN THE MIDDLE OF A UEFI BIOS UPDATE. It will result in system death. The UEFI BIOS Update should be run with administrator privileges. Right click your UEFI BIOS update and select “Run as Administrator”. Accept the User Account Control Prompt: Accept any other prompts and leave the system in peace to Restart and Update. Here is my Opti. Plex 7. After the update has proceeded you may want to check msinfo. BIOS version has been updated. The rest of this guide focuses exclusively on system with a UEFI BIOS. Enabling UEFI and Secure Boot. A UEFI Boot allows for the Globally Unique Identifier Table Partition Scheme (GPT) to be used opposed to the Legacy Master Boot Record (MBR). This partition scheme allows 1. TB drives and is more robust as there are multiple boot records opposed to a single boot record. Secure Boot as the name suggests only allows verified code to Boot. This code must have a Microsoft verified signature.
