I have no idea of what that tool is...but you extract the files and let me know when it is done and where I can download it.....
You may have to install the non-modified bios first and then it will probably allow you to back it up with whatever Bios Update Tool that is in the .EXE file....back that up and send it to me.
Yes, you will need to change the certificate....there are written instructions of who to activate windows....and yes, this slic will activate Windows 7 OEM when it becomes available.
Thanks to p4spooky and Busykid508. I'm using p4spooky's Asus A8N-SLI slic mod, and Busykid's GA-P35-DS3L slic mod. Both flash fine and show the slic 2.1 code at the right offset. Thanks again to you both.
