@SEK, OK, I will try again with your files in the evening. Did you use DOS or Windows? Is it possible, that a bad remove has some side effects? @TassieToo, I will also try your suggestion! You did it with DOS or Windows?
The best is u try this from dos (PURE MSDOS not comand windows), bacause in Windows 7 u need desactivate fully "Control of user acounts" and antivirus or u get errors, the cmd dont Work if u run with admin right.
Heinzi...I thought you had already tried it by both methods. If you have not, then SEK and TassieToo are right. You should try it as they both suggested using any Slic you want but with Jsign or the original Pksign. As whitedevil mentioned, jsign is the same as the original Pksign. I thought you had already tried SEK's advice and it didnot work. So if you haven't then do give it a try. Dos method is my preferred way and remember to be careful, bios updates can be sensitive so you donot brick your board.
I tested that too on a few boards I tried it on. I compared the bios backup and the bios after I updated from intel website. With Hex tools the Slic information was still present after update with intel bios. So no problems there. But from my experience, if you erase the Slic with the oa2intel to it seems the marker.bin information still remains. However, it is not going to do anything bad so it is not a problem. The normal bios updates from intel donot change the marker fields, so your bios slic should remain. But, it is good to know that it is possible for intel corp to release a bios update that can modify aspects of the Slic table, if they need to ever do that.
To be sure I tried it again with pubkey.bin asusmarker.bin and pksign.bin, but with the same result => no slic! @SEK, also with your files from intel.zip no slic is present. I did it from pure DOS! So why you are successful?
(1) Boot from DOS, and (2) execute the command : oa2intelwin.exe update PUBKEY.BIN marker.bin PKSIGN.BIN
