Mine dies at the same place yours is but is only happening with the HP 800 series 35w Desktop Mini PC. All are other HP models are updating the BIOS without an issue. I'm using 2.0.7 Invoke-CMDownloadBIOSPackage.ps1 and 1.7.0 ConfigMgr WebService.

I think this might be caused by the fact that some older models (in our case 2570p) do not use the HPBIOSUPDREC.exe. Instead they still use HPQFLASH.

The BIOS Update script expects to find HPBIOSUPDREC/HPBIOSUPDREC64 executable

The model machine I'm having an issue with uses the HPBIOSUPDREC/64.exe.
The ApplyBIOSPackage.log ends here

It will normally have all the info on what version it will be flashing with after that line.

Yeah, looks like you are having the same issue that I've been having. It doesn't parse the version number of the BIOS correctly. I'm not sure why he chose to do it the way he did. I modified the script to make work for us. Maybe it will work for you.

In the Invoke-CMDownloadBIOSPackage script, you need to replace the entire Switch statement in the Compare-BIOSVersion function with this.

You can see I've added some logic to handle the REALLY old HP BIOS versioning that used the F.XX format (yeah - we have some VERY old laptops....)

        switch -wildcard ($($CurrentBIOSProperties.SMBIOSBIOSVersion)) {

"ver" { $RealCurrentBIOSVersion = ($CurrentBIOSProperties.SMBIOSBIOSVersion -split "Ver.")[1].Trim() If ($RealCurrentBIOSVersion -like "F.") { $AvailableBIOSVersion = "00." + $AvailableBIOSVersion.Split(".")[1] $CurrentBIOSVersion = "00." + $RealCurrentBIOSVersion.Split(".")[1] } Else { $CurrentBIOSVersion = $RealCurrentBIOSVersion

                }

} default { $CurrentBIOSVersion = "$($CurrentBIOSProperties.SystemBiosMajorVersion).$($CurrentBIOSProperties.SystemBiosMinorVersion)" } }

Invoke-HPBIOSUpdate.ps1 now has a fix for the HPQFlash.exe and HPQFlash64.exe. As for the BIOS version matching, let me get back about that.

[NickolajA]

We've asked HP for a full list of possible BIOS version standards and will update the script in order to support them all once we know what to look for.

See fix from this issue that will be implemented in an upcoming version. #113
