This blog is about how I added BIOS Update in Task Sequence.

The main reason to modify the script is that the amount of different model we have in our production. Even though the majority of them are HP, but it was kept on growing.
The things you need to get it working are listed below.
ModelAliasExit.vbs
InstallBios.ps1
HPBIOS Updates
First Copy the ModelAliasExit.vbs to the script folder in the deployment share. This script is used to detect the Model of the machine. Please download it from the below location.
https://github.com/DeploymentResearch/DRFiles/blob/master/Scripts/ModelAliasExit.vbs
Once the script is copied, Edit the custom.ini file and add the below lines at the top.
[Settings]
Priority=Default
Properties=NeedReboot,MakeAlias,ModelAlias
After editing the custom.ini file, Copy the below script to notepad and save it as InstallBios.ps1.

Next, create an application using InstallBios.ps1.
Make sure the folder structure is correct as per the below picture.
Please download and copy the bios file to the source folder and make sure it the folder name is the same as the machine model name.
Once you copied the necessary BIOS file, you have to create two text files called BIOSName.txt and BIOSVer.txt.
BIOSName.txt file has the name of the BIOS File, and BIOSVer.txt has the BIOS Version
Next step is to add the application to the task sequence. Make sure you add the task it in the system restore section of the task sequence. I have created a group called 'BIOS Update' and add the application. A computer restart is necessary after the BIOS installation, you can add it in the script or create a computer restart task.
Update the deployment share and you are ready to run the task sequence.
