Dell Bios Version Check

The BIOS (Basic Input Output System) is one of the most important components on your computer that makes possible for the software to interact with the hardware.

Basically, the BIOS instructs the system the steps to perform various basic functions like starting up, and it also finds and configures the hardware, such as processor, memory, hard drive, and others.

Usually, the BIOS doesn’t receive updates regularly, but sometimes manufacturers (e.g., Dell, Lenovo, Asus, etc.) may need to roll out a patch to fix a bug, improve the system stability, or to enable a new feature on your Windows 10 device, which happens very rarely.

If you have a computer that features a BIOS, it’s a good idea to find out the version that is currently installed to see if you need to apply a new update to improve the functionality of your device.

In this guide, you’ll learn the steps to check the BIOS version installed on your computer running Windows 10, and what you need to do to install the new version.

Need to find or check the current BIOS version on your laptop or desktop computer? The BIOS or UEFI firmware is the software that comes installed on your PC motherboard by default and that detects and controls the built-in hardware including hard drives, video cards, USB ports, memory, etc. Nov 12, 2018 Check Your BIOS Version at the Command Prompt. To check your BIOS version from the Command Prompt, hit Start, type “cmd” in the search box, and then click the “Command Prompt” result—no need to run it as an administrator. At the prompt, type (or copy and paste) the following command, and then hit Enter: wmic bios get smbiosbiosversion. You’ll see the version number of the BIOS.

How to tell the BIOS version on Windows 10

Similar to previous versions, on Windows 10, checking the BIOS version is a straightforward process, just follow these steps:

Quick Tip: Alternatively, you can also use use the Windows key + R keyboard shortcut to open the Run command, and the type msinfo32, and click OK to open System Information.

You shouldn’t confuse BIOS with UEFI. They’re similar, but not the same. UEFI (Unified Extensible Firmware Interface) is the system available on newer devices that replaces the BIOS that overcomes many of the limitations. It’s also something that manufacturers can update more easily, even automatically using Windows Update.

How to update the BIOS on Windows 10

The BIOS is one of those components that never included an easy update mechanism. To find out if there is an update available, you can refer to the steps mentioned above to see your device “System Manufacturer” and “System Model”, and with that information, you’ll need to check your manufacturer’s support website to see if there is a new BIOS update.

If there is a new update, check the latest version available against the version installed on your computer. If the version is greater than the one you have, then you can go ahead and download the update.

Installing a new BIOS update doesn’t have one set of steps that you can use on every computer. The instructions will always vary per manufacturer, and even device model, as such make sure to follow the steps from your device manufacturer’s support website.

Usually, you’ll need to double-click an executable (.exe) file and follow the on-screen directions.

Original Post:

Ok, So for a long time, You couldn’t upgrade Dell’s Bios in WinPE x64 because they didn’t have native x64 bios installer, this has recently changed. – Download HERE
Mike wrote up a nice intro to the new utility HERE

I do all of our bios updates using the “Application Model” after the OS is laid down, so it has the 32bit subsystem, it works fine. But I know many people like to do it during PE. So I thought I’d play with it this morning and write up a script.

PreReqs for my script: Enabled PowerShell. Here are the things we’ve enabled: (Win10 1607 Boot Media)

Benefits of doing it how I’ve setup.

One Script works for all models, you just have to setup your folder structure to match the Computer Model in WMI.
Grabs Bios Password from File, you only have to update one File if you change your Bios Password
Creates TS Variables to avoid Rebooting if already on same bios version.
Creates Log file based on the Bios Update in the %temp%SMSTSLog Folder (X:windowstempSMSTSLogBiosFileName.log)
New Bios version release? No Problem, delete the old one, add the new one, update Package, done, no script change required.
It’s Fun

Package Folder Structure. Make sure the subfolders exactly match the WMI Model Name
Get-WmiObject -Class Win32_computersystem | Select-Object -ExpandProperty Model

Once you’ve created your Folder Structure, populate it with the latest Bios files for each model. (Just download and place in the folder, no renaming required)
Also, create a txt file in the package root called Bios.txt and put your Dell Bios password in that file.

Now, the PowerShell script will query WMI for the Model, look for the bios file inside of the corresponding folder and apply it to the system using the Flash64w.exe utility. (It will pull the password from the bios.txt file in the root of your package)

Updated Script from 3/17 Shown HERE:

Based on the Exit Code of the Bios Update, it will create a TS Variable you can use to reboot, retry if low battery or continue on with your TS. Nero blu ray player software free download. – More info about Dell Exit Codes here… I noticed it didn’t have them all though: http://en.community.dell.com/techcenter/enterprise-client/w/wiki/3462.dup-bios-updates. I trigger events based on Exit Code 2 (Successful but requires Reboot) and Exit Code 10 (Battery too Low). You can easily add additional Exit Codes and create custom variables to have your TS do other thing based on those Exit codes.

Now in your TS:
Create Dell Upgrade Bios Group, and set to only run if a Dell Computer:
select * from Win32_ComputerSystem where Manufacturer like '%Dell%'
Create Run Command Line Step:
powershell.exe -NoProfile -ExecutionPolicy ByPass -file .DellBiosUpgradePackage-2.0.ps1

Create another Group, This will run if the battery was too low to update the Bios. It will wait 10 minutes and try again. If the Battery is still too low after that Point, it will continue on without updating Bios. – You can easily put a step here that will popup a message box about how the Bios Didn’t update, etc.
SMSTS_BiosUpdateBatteryCharge = True
Command Line Step: powershell.exe -NoProfile -ExecutionPolicy ByPass -Command 'Start-Sleep -s 600'

It will then wait 10 minutes and try again, if successful, it will set variable SMSTS_BiosUpdateRebootRequired = true and continue onto the next group to reboot. If it fails due to battery again, it will set SMSTS_BiosUpdateBatteryCharge = True and show a Message that it probably has faulty battery. At this Point, you can click “OK” and let it continue, or turn it off and replace battery.

Create another Group which will reboot the computer and any other steps needed to get back to where you were before the reboot. (TS Variable = SMSTS_BiosUpdateRebootRequired equals true)
I added a “Format” step, just to ensure there was a place for the Boot Image to download too, this might not be needed in your environment depending on placement of the Bios Upgrade.

Ok, that should be it.

Cracked games ios no jailbreak 1. Note, I was running into some issues with the flashw64.exe utility from Dell, getting this error:

Once I added another line into the script to launch the software once with minimal arguments, it worked fine. I’ve contacted Dell Support to see if they have any ideas on that.

This is the line I added to fix that error:
start-process '$PSScriptRootFlash64W.exe' /'p=$BiosPassword /s'

Dell Check Bios Version Linux

However, changing the Argument Line & Update Bios lines fixed the issue, and I haven’t needed that. I’ve heard from commenters that people are still getting that message, so hopefully this will help. If you do get that message, Open a support issue with Dell, they will help address it. FYI, I’m also using WinPE 1607, not sure if the Build has anything to do with that error.

Update: 2/27/17 – Response from Dell:
Hello, Gary: I heard back from the BIOS engineering group. They said that they have not tested the utility using Powershell scripts. They do not support Powershell scripts. They only support use of the utility within a command prompt in Windows… It is also supported within WinPE (in a command prompt).

Update 2/28/17 – Call From Dell, they are escalating the issue to the BIOS engineering group and will be looking into the problem to see if they can resolve the issue when using it in PowerShell.

Update 3/17/17 – After working will BIOS Dev team, was able to rework the script to resolve the error I was seeing. Updated Script in Download and in this Blog Post.
