file bios lock where ?
I had some errors :
--- Flash Devices Found ---
W25Q128FV ID:0xEF4018 Size: 16384KB (131072Kb)
- Reading Flash [0x0000040] 0KB of 16384KB - 0 percent complete.
Error 317: Hardware sequencing failed. Make sure that you have access to target flash area!
FPT Operation Failed.

So I dumped the bios and the ME partition separatly
