Hello and greetings from YerMoney! This is my first time posting on this board, so let me start with telling you, that I'm deeply impressed by the threads I read tonite. I focused mainly on the 'works' of Bezalel, because I'm trying to figure out, which part of the DMI-table is checked to see whether the installed Windows is pre-activated or not. My first guess was the "Manufacturer"-string, since I was able to install a pre-activated (SLP) OEM Windows on a different mainboard after I patched the "Manufacturer"-string in this boards DMI-table. Well, this worked like a charme! Now it is interesting to see that you're trying to get rid of the problem to keep the pre-activation the other way round - by exchanging the OEMBIOS-files on the setup media (as far as I understand this thread). Anyway - patching the DMI-table or collecting a pool of different oembios-files - I greatly apreciate the fact, that this thread gives a collection of different manufacturer strings! So here is my contribution Oh, and by the way, a very informative tool is available from german compu-mag c't, named ctdmi.exe and bundled in ctbios15.zip - unfortunately only available in german.
