Dirty Environment Found with ASUS bios updates.

Question

Hello,

I'm trying to update ASUS BIOS, and during the update, the tool "afuwinx64.exe" asks, "System is going to shut down, are you ready? (Y/N)". If I press "Y" the update works but breaks task sequences. If I press "N," means no update, and MDT continue with the task sequence.

Can I add something before the BIOS update so MDT can continue from where it left off?

My task sequence is under State Restore "Custom Tasks," I also tried to add the following command lines before the BIOS update:

cmd /c reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v FilterAdministratorToken /t REG_DWORD /d 0 /f

cscript.exe "%SCRIPTROOT%\LTIApply.wsf" /PE /STAGE

cscript.exe "%SCRIPTROOT%\LTIApply.wsf" /PE /BCD

And the BIOS update itself:

New-PSDrive -Name "A" -Root $scriptDirectory -Persist -PSProvider "FileSystem"
 
$cmdPath = "C:\Windows\System32\cmd.exe"
$command = "/c cd C:\ProgramData\bios & echo Y | afuwinx64.exe Q170M-C-SI-4212.CAP /P /B /N /K /CAPSULE"
 
       
$baseboardModel = (Get-WmiObject -Class Win32_BaseBoard | Select-Object -ExpandProperty Product)

$ScriptDirectory = Split-Path -Parent $MyInvocation.MyCommand.Path
$FilesPath = Join-Path -Path $ScriptDirectory -ChildPath "Files"
$ModelPath = Join-Path -Path $FilesPath -ChildPath $baseboardModel

if ($baseboardModel -eq $baseboardModel -and (Test-Path $ModelPath)) {
    # Create destination folder if it doesn't exist
    $destinationFolder = "C:\ProgramData\bios"
    if (!(Test-Path $destinationFolder)) {
        New-Item -Path $destinationFolder -ItemType Directory | Out-Null
    }

    # Copy AFUWINx64.EXE, amifldrv64.sys, and Q170M-C-SI-4212 to the destination folder
    $filesToCopy = @("AFUWINx64.EXE", "amifldrv64.sys", "Q170M-C-SI-4212.CAP")
    foreach ($file in $filesToCopy) {
        $sourcePath = Join-Path -Path $ModelPath -ChildPath $file
        $destinationPath = Join-Path -Path $destinationFolder -ChildPath $file
        Copy-Item -Path $sourcePath -Destination $destinationPath -Force -Verbose
    }

    # Get Bios File Name (Uses the Bios ROM file in the model folder)
    $BiosFileName = Get-ChildItem -Path $ModelPath -Filter *.CAP -Recurse -Verbose | Select-Object -ExpandProperty Name

    # Get Bios File Name (No Extension, used to create Log File)
    $BiosLogFileName = (Get-ChildItem -Path $ModelPath -Filter *.CAP -Verbose | Select-Object -ExpandProperty BaseName) + ".log"

    # Set Command Arguments for BIOS Update
    $exeName = Join-Path -Path $destinationFolder -ChildPath "AFUWINx64.EXE"
    $ROMName = Get-ChildItem -Path $destinationFolder -Include "*.CAP" -Name
    $logFilePath = Join-Path -Path $destinationFolder -ChildPath "Files\$deviceID.log"
    $parameters = "/P /B /N /K /CAPSULE"

    Set-Location -Path $destinationFolder
    #Execute-Process -Path $exeName -Parameters $ROMName, $parameters
    Start-Process -FilePath $cmdPath -ArgumentList $command -Wait -NoNewWindow 
    

    Write-Host "Performing BIOS update for $baseboardModel."
}
else {
    Write-Host "No BIOS update required for the detected baseboard model: $baseboardModel."
}

I'm also struggling with "Echo Y", I want it to say "Yes" in the prompt automatically.

Thaaaanks!

Hi, @lupinlicious

Thank you for posting in Microsoft Q&A forum.

Can the afuwinx64.exe run silently? How about add a "Restart computer" step manually?
