i dont understand why you are using that program as by downloading the latest BIOS and flash it to your motherboard will remove any SLIC 2.1 signatures, what do u want to mod?
Awesome LatinMcG! The 2nd link is interesting. It only mentiones z77 and x79 board. It's an old thread, so I'm pretty sure this also applies to z79 boards as well. All test it and report back if anyone is interested.
