Hi,
I need comparing BIOS version for a script and exit the script if the current BIOS is newer than the one in the package.
My problem is the BIOS name is very different from each manufacturer:
Exemple:
Toshiba: Version 6.80
Version 6.90
Lenovo: N2XET26W (1.16 )
N2XET27W (1.17 )
For Lenovo, I tried comparing both BIOS with [system.version] but the input is incorrect.
What should be the good way to compare BIOS versions and getting if the new BIOS is newer or older than the actual one?
Thanks,

Try Get-WMIObject -Computer XXXX -Class Win32_BIOS
You should be able to replace XXXX with the name of an array of computer names. You can then use the information to sort out what part(s) of the data returned for each machine you need to compare to the list of names of the BIOS you'll be comparing them to.
Hi,
So your suggestion is to put the informations in an array then sort?
Thanks,
No, I'm suggesting that you examine the information you get from the WMI Query. You (supposedly) have a list of the BIOS data that you want to check against the WMI data. Whether that list is suitable for making a direct comparison against one property in the WMI results I don't know. Perhaps you need to take various parts of the WMI data and compare them against parts of the identities in your data, or build a construct a "name" from the CMI data to match the data in your list.
The array "XXXX" in my reply was a list of computer names. The WMI query will return a list of WMI objects that you'll store in another array. You can sort the WMI results if you like, but I don't see how that would help anything.
WMI is the best way to determine the version of the BIOS installed in the system. Note that modern systems use UEFI; I will assume you are familiar with that. The following should get you started.
I doubt there is a standard interface for determining the current version available from the manufacturer.
Hi,
The issue is not to get a BIOS version but to compare the one already install on a computer with the one I need installing. If the one I need installing is older than the one already install then exit the script.
Thanks,

Hi,
The WMI Win32_BIOS class returns complete information about the system BIOS including manufacturer and version. You can contact the manufacturer to confirm how to determine the version of the BIOS firmware file.
