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.
Here are the instructions:
1. Take your current executable BIOS flasher.
2. Unpack with any unzip software
3. Find "platform.ini" file
4. Edit following lines with Notepad
[BackupROM]
Flag=1
FilePath=c:
FileName=<put bios name here>.BIN
5. Flash the same BIOS again with the modified platform.ini
6. After reboot you will find dumped current BIOS on C drive
