XP lee muy poco el bios, luego en el 98 entra en modo de pruebas de fallo y fijate si no tienes algo en error, desile que examine la maquina buscando nuevo hardware.
Si, AF tiene razón, Win98 es tan sensible que una modificación de BIOS que suponga tener que reinstalar componentes del sistema operativo lo puede tirar abajo. La parte buena es que te deja reinstalar el sistema encima, así que igual esa es buena solución. O entrar en modo a prueba de fallos, borrar todos los componentes del sistema y hacer que los detecte de nuevo.
