Starting from 2012 Insyde Corp. implemented RSA algorithm to crypt their bioses to avoid modding. To unpack such bios with Phoenix tool is impossible. But we 100% sure BIOS rom stored in motherboard in decrypted variant. So easiest way to get it - make backup of current BIOS before flashing new one. But we also can flash over the same version of bios.


Here is instruction:


1. Take your current executable BIOS flasher.
2. Unpack with any unzip software
3. Find platform.ini file
4. Edit following lines in it

[BackupROM]
Flag=1
FilePath=c:
FileName=<put bios name here>.BIN

5. Flash the same BIOS again with modified platform.ini
6. After reboot you will find dumped current BIOS on C drive
