PowerShell WMI – Querying BIOS informations

Hi Guys,

I will start a small blog post serie with PowerShell functions I wrote that query WMI of remote computer. Here is the first function:

Function Get-BIOSInfo {
    <#
        .SYNOPSIS
        Describe purpose of "Get-BIOSInfo" in 1-2 sentences.

        .DESCRIPTION
        Add a more complete description of what the function does.

        .PARAMETER ComputerName
        Describe parameter -ComputerName.

        .EXAMPLE
        Get-BIOSInfo -ComputerName Value
        Describe what this call does

    Param(
        [String]$ComputerName = $env:COMPUTERNAME
    )
    Begin {
        # Win32_BIOS: http://msdn.microsoft.com/en-us/library/aa394077(VS.85).aspx
        $Win32_BIOS = Get-WmiObject -Namespace root\CIMV2 -Class Win32_BIOS -Property BiosCharacteristics, SMBIOSBIOSVersion, SMBIOSMajorVersion, SMBIOSMinorVersion, Version -ComputerName $ComputerName
    }
    Process {
        Write-Verbose -Message 'BIOS gathered information:'
        $Output = @()
        $Win32_BIOS | ForEach-Object {
            $BIOSInfo = New-Object -TypeName PSObject -Property @{
                SMBIOSBIOSVersion = $_.SMBIOSBIOSVersion
                SMBIOSMajorVersion = $_.SMBIOSMajorVersion
                SMBIOSMinorVersion = $_.SMBIOSMinorVersion
                Version = $_.Version
                BiosCharacteristics = $_.BiosCharacteristics | ForEach-Object -Process { Invoke-BIOSCharacteristic -BIOSCharacteristic $_ }
            }

            $BIOSInfo.psobject.Properties | ForEach-Object {
                Write-Verbose -Message "`t$($_.Name): $($_.Value)"
            }

            $Output += $BIOSInfo
        }
    }
    End {
        Write-Output -InputObject $Output
    }
}

This function will provide you basic information over the BIOS configuration of the computer you want to query.
For the purpose of this script I used another function I wrote to match the BIOS Charactics integer with features names or configuration, you can find it there.

See you,
