Yes. Enable Internet sharing on your Mac, connect an ethernet cable between her computer and yours (is your network card "autosensing?"-you may need a crossover cable if it isn't.). On her computer, you'll have to install networking if it isn't already. You can tell by whether Win98 asks for a password when it starts up-if it doesn't, networking isn't installed. In that case, you'll have to go to "Add Programs|Windows Components" and check the box for networking-you may need the Win98 installation disc for it to complete the installation. After a restart on the Windows machine, you should be set.
