BUG: Multiple Disk Install Causes Error in Windows 98ID: Q201678 
  | 
During the installation of a driver using inf files, Windows 98 displays an error dialog box if LayoutFile= is used and the installation spans more than one disk.
When using an inf file, the [SourceDisksNames] and [SourceDisksFiles] sections can be included in a separate inf file. This inf file is referred to by the LayoutFile= entry in the [Version] section of the main inf file.
Under Windows 98, if the installation requires more than one disk, Windows 98 displays an error message if the LayoutFile= entry is used. Single disk installs are not affected by this problem.
A workaround for this problem is to include the inf files on all the disks of the installation.
Another known workaround is to include the contents of the layout file (the [SourceDisksNames] and [SourceDisksFiles] sections) into the main inf file.
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.
