[Solved] Intel HD 530 - KP on setting ig-platfrom-id 10.12

[ironman2]

With some research over the forum, I found out that the Intel HD 530 can be made working by adding Inject Intel and ig-platform-id.
When only Inject Intel is enabled, I can boot properly with graphics detected as Intel HD 530 5MB, (with no acceleration - obvious) - VGA

<key>Graphics</key>
<dict>
        <key>Inject</key>
        <dict>
            <key>ATI</key>
            <false/>
            <key>Intel</key>
            <true/>
            <key>NVidia</key>
            <false/>
        </dict>
        <key>ig-platform-id</key>
        <string>0x19120000</string>
</dict>

Then I added the ig-platform-id with Inject Intel true as shown, and when I do so - getting KP
Multibeast -> Intel HD 530 -> same KP

Also, I tried the PikerAlpha graphics glitch fix,
Also tried this,

<dict>                 
    <key>Comment</key>
    <string>10.11-SKL-1912000-4_displays</string>
    <key>Find</key>
    <data>
    AQMDAw==
    </data>
    <key>Name</key>
    <string>AppleIntelSKLGraphicsFramebuffer</string>
    <key>Replace</key>
    <data>
    AQMEAw==
    </data>
</dict>

But I get KP when in all cases when I enable ig-platform-id.

Is this something related to the DVMT, but unluckily my bios don't have an option to set the DVMT, but there is an option to choose the Intel HD graphics/ automatic.
I'm on 10.12, any help is appreciated.
Please see the KP screen capture attached.

Thanks for replying this fast.

I believe I should use this patch, after converting to base64.
And also clearing the kernel cache by booting into an invalid ig-platform-id (0x12345678) first.
Another doubt in my case - I was using

 ig-platform-id = 0x19120000

Hoping this is the most commonly used in all guides i found, is this really the ig-platform-id that works for my IGPU or am I doing anything wrong?

Use a plist editor to add the patch... such as Xcode or PlistEdit Pro.
The editor will convert to base64 for you.

So I'm using the plist editor to add:01030303 00002002 00005001, into the data class in plist editor it is identifying it as 12 bytes. am I doing this correct ? screenshot attached

Assuming you're using ig-platform-id 0x19120000, looks correct.

I don't not know how to say thanks.
Now working seamlessly, no artifacts!

Looking forward to create a thread on this.
