And in case of installing Windows 3.11, this was even more hilarious because of the fact that installer did not want all the disks in order, but only first five or so and then proceeded to demand disks in essentially random order, and in some cases the numbering on disks themselves did not match installers idea. I vaguely remember that printer drivers that installer expected on disk 7 or 8 (depending on whenever you used "Standard install" or "Expert install") were actually on disk 9.
