Official support for 98/ME may be done, but unofficial support is available.

Many vendors are removing everything 98/ME related from their sites. Visit your vendors site and get copies of everything there that's for 98/ME, especially drivers, even if you don't need it. Someone else will. When properly configured, 98 is a very stable and reliable OS, too good to let die just because a corporate giant isn't profiting from it.
