<p>So on newer Intel 300 series motherboards, manufactueres started pushing for a new type of system clock: <strong>AWAC</strong>( <strong>A</strong> <strong>W</strong>eird <strong>A</strong>ss <strong>C</strong>lock).

<p>As you can see we found the <code>STAS</code> in our DSDT, this means we&apos;re able to force enable our Legacy RTC. In this case, <a href="https://github.com/acidanthera/OpenCorePkg/blob/master/Docs/AcpiSamples/SSDT-AWAC.dsl" target="_blank">SSDT-AWAC</a> will be used As-Is with no modifications required. Just need to compile. Note that <code>STAS</code> may be found in AWAC first instead of RTC like in our example, this is normal.</p>
<p>For systems where <strong>no <code>STAS</code></strong> shows up <strong>but</strong> you do have <code>AWAC</code>, you can use <a href="https://github.com/acidanthera/OpenCorePkg/blob/master/Docs/AcpiSamples/SSDT-RTC0.dsl" target="_blank">SSDT-RTC0</a> though you will need to check the naming of LPC in your DSDT</p>
<p>By default the SSDT uses <code>LPCB</code>, you can check what your system uses by just searching for <code>Name (_ADR, 0x001F0000)</code>. This address is used for Low Pin Count devices(LPC) but the device name can vary between <code>LPCB</code>, <code>LBC</code> or <code>LBC0</code>:</p>
