You can also automate Setup when both the Windows 98 files and the batch file are located on a server that can be accessed by the local computer.
To do so, start the computer running the existing network client software. Connect to the server or drive that contains the Windows 98 source files. Note that the network administrator can include this step in the logon script to avoid user action.
At a command prompt, run Windows 98 Setup by specifying the batch file that contains the Setup script. Use the following syntax \\server_name\windows\setup.exe batch.inf where server_name is the name of the server, windows is the folder that contains the Windows 98 files, and batch.inf is the name of your Setup batch file.
NOTE: If Windows 98 is installed from a server, the location of the source folder is stored in the registry. When you add a device or require additional support files to run Windows 98, Setup automatically attempts to retrieve the files from the same location on the server. This eliminates the need to maintain a permanent network connection on the computer and makes it easier to modify the configuration of a computer in a networked environment.
note that the article discusses automated setups but I am pretty sure you can do it manually.
