You still don't know that HFSLIP can slim down W2k the way nLite does it?
You possess a tool that can do the things nLite does with even more customatization!

First of all you should read TommyP's instructions about creating removal files here - they are not so difficult but when you learn them you'll get a real power in your hands to make your own Windows 2000

I don't have ISDN adapter. I gess the drivers for them can be deleted from my installation source.

isdn.rdv
isdn.rem
Did you notice files with XX extentions? They are just the title for the driver. Maybe you need some of the drivers. In that case just delete their entries from RDV and find corresponding INFs in REM.

PS I have a feeling I may forgot to include one or two files from DIDIVA.INF.
