Does anyone know where the information comes from when you run WINMSD. I'm tring to detect the system model so I can install the appropriate drivers as it's too complex to unpack them and add entries to PNP OEM path.

First result @ Google:

Winmsd in Windows 2000 will actually run Msinfo32 -

mmc.exe /s "C:\Program Files\Common Files\Microsoft Shared\MSInfo\MSInfo32.msc"

You can use MSInfo32.msc /report <filename> to export system information to a text file (this is a pretty big file, 1.5MB here).

What are you trying to find out exactly? I've looked at it on several PCs here, and all of them said System Model: "System Name" (and System Manufacturer is... "System Manufacturer"!) Or does it show something else on some PCs? Lots of infos can be easily retrieved with WMI in vbscript (it's VERY powerful), but I'm not sure what you're trying to get to here...
