<p>MyDNA: </p> <hr /> <div>Starting from 2012 Insyde Corp. implemented RSA algorithm to crypt their BIOSs to avoid modding. To unpack such BIOS with Phoenix tool is impossible. However, we are 100% certain that the BIOS rom stored in the motherboard is a decrypted variant. The easiest way to get it - make a backup of current BIOS before flashing with the new one. But we can also flash with a modded BIOS version over the same BIOS version number.<br /> <br /> <br /> Here are the instructions: <br /> <br /> <br /> &#039;&#039;&#039;1&#039;&#039;&#039;. Take your current executable BIOS flasher.&lt;br /&gt;<br /> &#039;&#039;&#039;2&#039;&#039;&#039;. Unpack with any unzip software&lt;br /&gt;<br /> &#039;&#039;&#039;3&#039;&#039;&#039;. Find &quot;platform.ini&quot; file&lt;br /&gt;<br /> &#039;&#039;&#039;4&#039;&#039;&#039;. Edit following lines with Notepad<br /> <br /> &lt;tt&gt;[BackupROM]&lt;/tt&gt;&lt;br /&gt;<br /> &lt;tt&gt;Flag=1&lt;/tt&gt;&lt;br /&gt;<br /> &lt;tt&gt;FilePath=c:&lt;/tt&gt;&lt;br /&gt;<br /> &lt;tt&gt;FileName=&lt;put bios name here&gt;.BIN&lt;/tt&gt;&lt;br /&gt;<br /> <br /> &#039;&#039;&#039;5&#039;&#039;&#039;. Flash the same BIOS again with the modified platform.ini&lt;br /&gt;<br /> &#039;&#039;&#039;6&#039;&#039;&#039;. After reboot you will find dumped current BIOS on C drive&lt;br /&gt;</div>
