Hi! After replacement of motherboard, new board have missing MSDM table with license key. I was try to flash old bios, laptop works fine , but standard dell flash update utility hang on start, so it can not flash-update. With original bios, came with new board utility is work fine except installation of original USB-FLASH with win8.1 on it. (it asks key during install, please do not write about: write by hand, not needed, no sense, no useful, i just need to add original key to) Study many of sources about adding MSDM table, but no one is give a successful result. using afuwin64 with /a key flash something , but MSDM table have not appear after flash/reboot. mega - NYY2AJpZ#kfMzAHX5T8leRTgNdQhdz_59c2ozAfQdvobe9AtFvwE thanks in advise.
