Its one of my senior's Inspiron 7520. It came with pre-installed Windows 7 Home Premium. I have upgrade the bios from A07 to A09 and installed a clean copy of Windows 8 Pro. After the upgrade, it shows 2 identical SLICs. RW report and SLIC Toolkit report -> http://rghost.net/44330015 BIOS backup -> http://rghost.net/44331055 Any thought??
