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>)

<g>

>You can always check the requirements in the last portion of each class's documentation, for BIOS is in this link: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmisdk/wmi/win32_bios.asp

Thanks for the 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.
