A partir de ce point, nous allons utiliser principalement la ligne de commande pour configurer et démarrer QEmu. Ouvrez donc une Invite de commandes et placez vous dans le dossier C:\QEMU.
Une manière simple d'avoir un aperçu des options de QEmu est de taper :
C:\QEMU>qemu
Ce qui devrait afficher quelque chose ressemblant à ceci :

Bon, plutôt indigeste, au premier abord, mais ça donne une bonne idée de ce que QEmu est capable de faire..
Commençons par les options essentielles à l'utilisation de l'émulateur. Nous verrons les autres plus tard.
