I just tried the IFI_Loader on windows ME, what it 'does not work on', and it works just fine!

Granted, I have VB6, what it was written in. But still...
If you want to know how, extract the cab (it's a standard cab, not one of those funky things most installers use), register the DLL's and OCX's (regsvr32 PICBOOT.dll) and run IFI_Loader.exe.
Does any one know exactly why it 'does not work' on ME?
