    Just want to check and make sure I am looking at the right stuff!!!

    I have the MK III and want to replace locked BIOS MB with a new one. I have found DL31U1866AAA as a MK IV board. Is this the one I want?

    Thank you all!!!

    Got a Mk Iv unit coming with less than 6000 hours!!!! It's hurting, but has GPS, a unlocked MOBO, and probably some other stuff I can use. Sheepman has been helping me through this and gets the kudos!!

    I personally have never "entered" into the real working of a 19 until today. Watched many a video and Bob Johnson and his crew have details I never thought of! Kudos to Bob Johnson.Com also!!! I broke it down rather neantrodalicaly, but now have the G2 (intel) to put it all back together.

    Thanks all who walked me through this adventure!! I can say now, I won't feel so bad working on these in the future and may acquire more.

    Also found a guy on eBay who worked with me and really helped me out. He had 8+ units of Mk Iv's to sell, but they were in different states of disrepair. He found the lowest hour one, with a GPS, and unlocked, and gave me a private link to buy it.

    I will share info if you desire Mk IV stuff. He only has 7 left after me........

    Thanks again all!!!

    Hey Shawn, great idea!!! I had to disable driver signing in Win 8, re-install, and problem repaired!!! Thank you!! Also, if you have win 8.1, you need to disable the auto driver update in the CP, System, Advanced Settings, Hardware Tab. We will see if that does the trick. It actually updated them back after I loaded the right ones.

    Found out a whole lot more and I think is this why I was unable to get the SD Card to work on the Mk II also!!! Good read to bypass the driver signing!!


    How to Disable Driver Signature Enforcement in Windows 10/8/7 64-Bit
    May 4th, 2015 by Admin Leave a reply »
    In 64-bit operating systems starting with Windows Vista, Windows will load a kernel-mode driver only if the driver is signed. It was designed to prevent unsigned device drivers (or kernel modules in general) from being loaded and executed. After installing an unsigned device driver, it will always result in a blue screen of death during the startup process.

    The problem is that many devices ship with unsigned drivers. Today, we’ll show you 2 methods to disable Driver Signature Enforcement in Windows 10, 8, 7 (64-bit) so you can then install / load unsigned drivers without problems.

    Option 1: Disable Driver Signature Enforcement Completely

    Open a Command Prompt with admin privileges. In Windows 10 or 8, just press the Windows key + X and then select “Command Prompt (Admin)”.
    Type in the following command and press Enter.
    bcdedit /set testsigning on
    You should receive “The operation completed successfully” message.

    Close the Command Prompt and restart your computer. From now on, you will be able to install or run any unsigned driver without problems.
    If you need to enable the Driver Signature Enforcement again, run this command instead:
    bcdedit /set testsigning off

    Anyway, here is the addition completely up and running on the left!!! IMG_0271.jpg

    Tonight, I am only working on the "newer" Mk Iv!! I cannot believe it is up and running flawlessly! The only reason it is... is because of all of the great responses and interaction I had with a lot of folks on this forum.

    Again, my many sincere thanks for bringing this to fruition!!!

    Upgraded to 8GB of RAM tonight from 4 on this rebuild, no problems!!!!! Seems this build is working very nicely now! Have an emissive KB coming tomorrow, and this older, but newer, MK III/MK IV will be a twin to my much older, very well used, but still somewhat working MK IV. Well worth the $250 or so I have spent on doing this, plus all of the marvelous feedback from all here. I do appreciate all of experience and expertise with helping me out!!!

    Alrighty then,

    Finished my last 2 additions.... Emissive KB and 750 GB Samsung EVO 840 SSD. All is working great.

    New note on the "Test mode to disable driver signing..... When you do, several watermarks appear on the lower right corner of the screen. To get rid of this, and I did it and it worked flawlessly, follow the instructions below:

    1. Go to the Softpedia link below, and download My WCP Watermark Editor.
