Whats the output from "SLIC Toolkit"? Dump ok? In your RWe-report SLIC-table is present and valid. Did you install the right certificate-file? You must use the exact matching cert for v2.5, there exists only one cert, name: DELL-DD981F15.XRM-MS
SLIC Toolkit didn't work with GPT harddisk. my Win7 worked with DELL SLIC 2.6 and Dell Cert before. not work with this bios. I got a good retail key and activated my Win7 again, so i don't need SLIC any more.
