If you are an NT user who is configured for PPP access
and will be installing Remote Access Service, you may be
required to insert your Windows NT System CD-ROM to
copy files, so you should have this handy before starting.

Remove the cover from your computer. Refer to the manual that
came with your computer if you need instructions for your model.
