Hi Hugo
>Eventhough you can install WMI in a Windows 98 computer, not all classes are available for it, and according to the documentation, Win32_Bios requires WIN NT 4 SP 4 or better (of course anything is better than NT 4 <g>)

>You can always check the requirements in the last portion of each class's documentation, for BIOS is in this link:

No problem I just installed the file as suggested by Craig on a W98 machine and ran your code and it ran w/o a hitch, the only thing is the sr. no. on the machine I tried returns .NULL.
