<p>To fix the ECs found in laptops, we'll be renaming them to look like the ones macOS expects. The reason for this is that many laptops break when you turn off their EC with an SSDT. So this is why we can't use the fancy SSDTTime to make a patch for us.</p>
|
||||
<p>To find out what EC you have, open your decompiled DSDT and search for <code>PNP0C09</code>. This should give you a result like this:</p>

<p>This SSDT is used to force enable our GPI0 for VoodooI2C to connect onto.</p>
|

<p>With most modern laptop DSDTs, there's a variable called <code>GPEN</code> or <code>GPHD</code> which are used for setting the status of the GPI0 device. For us, we want to enable the device.</p>

|

<p>So first things we need to do is find out what variable is used to enable our GPI0 device, lets open up our decompiled SSDT and search for <code>Device (GPI0)</code>. Should give you a desult similar to this:</p>

</code></pre><p>What we want is for this to always return <code>0x0F</code> when booting macOS, so we want to make an SSDT that will return <code>GPHD == Zero</code> in macOS.</p>

<p><strong>NOTE that you may have the other way around where GPHD needs to be set as <code>One</code> to return <code>0x0F</code></strong>. And your device name may also be different, don't throw random SSDTs in thinking it'll work</p>

<p>Once you found the variable and what it should be set to, grab a copy of <a href="https://github.com/khronokernel/Getting-Started-With-ACPI/blob/master/extra-files/SSDT-GPI0.dsl" target="_blank">SSDT-GPI0.dsl</a> and make the required edits. Then clean up with compiling it</p>
