Thats the problem when you ask some noobs to make a modded BIOS.... Sorry guys, but using tools like the Award/AMI SLIC tools by AndyP are not the only things you have to know for doing some working mods!
Would just like everyone to know, that the MSI GX-620 (1651) already contains the slic 2.1 in the newest bios on the msi website. Win 7 installed and activated using just the MSI cert.
