Have u tried via efi shell ?

I think this bios is RSA Signed (maybe cannot be modded)

1. Decompress setup

2. Edit file "platform.ini" and change Flag=0 to Flag=1

[BackupROM]
Flag=1
FilePath=c:
FileName=

3. Execute "InsydeFlash" program, the program will hang a little bit because is backuping bios... after backup is finished will be asked to flash bios (dont flash) close program.

4. Search for bios "biosname.fd" on c: drive

5. Post here

I had to add [BackupROM] and the rest to make the setup to generate .fd file. There are 2 files. One is RSA free. Thanks for your help

Hi friends,
It's not a problem to extract original Bios version file from Site file or laptop !
Problem is to bypass the RSA Signature Check !
Donovan6k has done, but only way to reflash Bios Mod is using an HW SPI Programmer !
