Yeah, the switches you tried are actually for use with AFUDOS v 2.x from ASUS. MSI uses AFUDOS v 4.x from AMI.
I am positive I have used slic 2.1. There is some other problem. Can you post the screenshots of slic tool kit v3.0? of the flashed bios. Perform a clean installation of windows from an untouched original DVD and make sure you are *not* using any loaders.
