    Yes, this is something, I'm also interested in how to. Which tools are used and what has to be inserted or deleted in the bioses

    Really didn't understand why you guy's try something which isn't really supported. So those older MB's which using CPU which not having the min. required functions. Even if you'll get some of them work, on what cost? I didn't mean money, I mean what other limitations will come up than? Or what you'll not able to use any more, etc. etc.!The time that old CPU's and MB's were actual were at the tim,e before even SATA were available, or if just the first 1.5Gbps SATA! The whole architecture of CPU's, Chipset's and even MB's has changed in the meantime.

    If you didn't have the money for to buy the newer hardware, stick with the old one and use the OS which could fully work with it!

    And for BIOS Mods, there special forum for just that here at MDL! Post your request of an BIOS Mod there, that would be the appropriate way!

    This is not the point for me to get an old machine running. What I like to know is how it is done for learning purpose only. As I still have such an old device here, I'm simply curious if it can be aplied to that particular bios/machine. That's all :D

    Maybe that would be possible?! But sufficient? I hardly believe that! What you'll achieve at one part may lose on an other! For learning? Fine! In real it would be waste of time because the outcome will not pay off for the time used and also useless for newer system.

    Anyway it's a personal decision to do or not to do! Good Luck!

    My curiosity leads me to that point as this old IBM machine did a great job for years first with XP, then with W7 on it and it went absolutely smoothly with 7. If I can mod the bios into a working one for W8 I'm done on this. I got plenty of time to do such things and have no need to make money out of it, so what ...

    I "played" quite a bit with the Kernel of either Windows 7 and Windows 8 and see quite a lot differences in it. And those differences pointing to different hardwae. But I wasn't go in the deep with that because my interest were because of the Memory barrier of 3.5GB which I had working up to 32GB in windows 7 but Windows 8! May I'll start again if I get a bit more time. At the moment I've get my companies paper ready for the Revenue Department!!

    Sure
    Have you ever programed control chips. Like for satlite card programers. It is the same thing or for CNC machines.
    I can send you the programing code if you like. just PM me if you would like it.

    Which IBM do you have. I have a mod BIOS for a T40 and that BIOS worked on a T-42

    No, it's directed at the person whom I quoted in that post. So you could say it was actually in defense of you ;)

    No, it is a IBM-M50 desktop, couple of years old. I replaced all bioses by modded ones for Slic2.1 purpose in 2009 I guess to run W7ultimate OEM. If you like to dig into it, I can provide the bios data which I need to search for first. Might be a challenge to get these units running with W8 as I know lots of colleges here within Red Cross using this kind of machine all the time. Very reliable machine!

    My old computers are worthless junk anyway. Even if I can't or don't intend to actually use Windows 8 on my old computers, the loss is small. In return, I gain knowledge.

    What you are looking for is where the CMOS or BIOS checks the CPU and then gives that info to the OS.
    What you need to do is when the CMOS checks the CPU info and does not see a feature instead of it reporting that the feature is not there it reports that it is there.
    But you have to watch that it does not try to load instructions for that feature or the system will not post.
    All you want it to do is show the feature is there for the OS.

    That's not true. It has nothing to do with Bios. It's the "KiCpuId" call in ntoskrnl that you have to patch or the test afterwards. Bios is not involved at this point, only the cpu and its msrs.

    that would be awesome, I was looking for something like this in this topic: forums.mydigitallife.net/archive/index.php/t-41459.html

    anyway, my mb bios is this one: dlcdnet.asus.com/pub/ASUS/mb/sock478/p4v800d-x/P4V8D704.zip

    The cpu is a Intel Pentium 4, 2633 MHz Prescott E0 (18 x 146) (oc'd) instructions: x86, MMX, SSE, SSE2, SSE3
