Ok…I’m going crazy at this point. I’ve followed the steps outlined in this forum for “unlocking/unhiding” Bios settings about 50 times now over the past two days, but it never works. I’m trying to unhide the IOH bifurcation section, so that I can set one of my PCIe ports to 4x4x4x4, which the IFR shows that it supports. However, I can’t seem to get it to work. I’m humbly reaching out to anyone on this forum that has experience with this issue and might be willing to assist. Thank you.
