If what you mean is to skip the prompts Windows setup has to go through during installation for each PC, Windows 98 has a "hidden" tool in the installation CD called Batch (or something like that) whose sole purpose is to gather the installation settings of your current Windows.

This will result with an ini file you can pass as an argument to Windows' setup.exe,
e.g. d:\win98\setup.exe c:\mywin98settings.ini
since all install information is already supplied, setup will just breeze throught the entire setup process after just a few clicks. Of course this won't affect programs that doesn't come with Windows itself, but it's a start.
