Well, actually it will work, but not by just inserting the DVD in the drive.
This is the method, taken from my install guide
But is that method retail? From me reading it it seems as if you have to backup all system etc every time you want to update? I would prefer a vanilla style method where updates aren't so tricky. For example if I had lots of apps I'm guessing I would have to back it all up?
Please correct if wrong or if you know of a way I can install Snow Leopard on Dell E520 retail style. Please also let me know if I am using these 'retail' 'vanilla' terms in the wrong sense!
also - anyone know if a vanilla (there i go again) snow leopard (or even leopard) install for the Advent 4211?
