This is the third version of the script solution; it is very simple. You detect make/model in any way you would like to, create a rule based on BIOS version, if the rule match, nothing happens, otherwise it runs any command you want. That said, you could use this for other task as well. Most common question is “does it work with any Make/Model”`No, there are some vendors that does not provide the ability to run a BIOS upgrade silently without reboot without control, that is, the darn thing reboots immediately and that usually breaks the Task Sequence. I have one thing for those vendors to say “Shame on you!”

here are older posts on the subject

Detect the Model

The detection in the script is actually whatever you want, it is just a “If-then”  here are two sample lines detection that you will find in the script

if($((Get-WmiObject Win32_ComputerSystem).model) -eq 'HP EliteBook 8560w'){}
if($ModelAlias -eq 'HP EliteBook 8460p'){}

Use the detection method for each model you like, very simple

Detect the BIOS version

This is also not that hard, here are 2 sample lines from the script

if($((Get-WmiObject Win32_Bios).SMBIOSBIOSVersion) -ne '68SCF Ver. F.63'){}
if($((Get-WmiObject Win32_Bios).SMBIOSBIOSVersion) -ne '786G1 v01.27'){}

Store the upgrade files

The upgrade files are stored with the model name, like this:

The Silent Command

You also need to figure out the command, not really hard, download the bios upgrade, read how to run it from a command line, update the script and you are done, here is a sample of one of those sections.

$Exe = 'hpqflash.exe'
$Location = "$SCRIPTDIR\Source\HP EliteBook 8460p"
$Executable = $Location + "\" + $exe
Set-Location -Path $Location
Invoke-Exe -Executable "$Executable" -Arguments "/s /f 68SCE.CAB" –Verbose

Run the script

in MDT you can import the folder with the script as a application and set this as the command line:

PowerShell.exe -ExecutionPolicy Bypass -File Install-BIOSUpgrade.ps1

In ConfigMgr you can import this as a Package and then run the command line the same way

It is also possible to run this outside of a task sequence if you like, it works as a stand alone script, however, you cannot use the integration with MDT of course.

If you want it is possible to add a custom property in customsettings.ini, something like “NeedReboot”, then you can add the following to happen if the BIOS has been upgraded

$tsenv.Value(“NeedReboot”) = “YES”

If you then in the step after this, set a condition on a reboot step, well then it will reboot when needed, otherwise not, you can read about that in one of my old postings here

It was needed.
