unlocking Msi Z170A pro carbon bios (E7A12IMS.140)

[racminer]

Hi. Need help unlocking Msi Z170A pro carbon bios (E7A12IMS.140).

I am trying to set all pci socket to gen1 mode. I can only set to gen1 two pci sockets (named peg0 and peg1 in bios).

I understand that the tools are AMIBCP and HEXEDITOR, ans I need to un-hide the chipset menu ... so far with no success .. HELP.

Hi everyone,

I've been able to solve my problem. I've modded the bios using AMIBCP only. I've uncovered the sub-Setup>Settings>menu named "For SA test GRUOP" . And there, I was able to set all PCIe's to Gen1.
all my usb risers work now.

Case solved.
