Hey there everyone. I have no idea how this happened but I have enabled Intel RST on an Asus Maximus XIII Extreme Glacial as I was preparing to reinstall Windows for a clean wipe, and my NVMe drives are no longer detected. Windows had just slowed down and I wanted a clean start from a fresh install. I backed up all my data, so I am not worried about that. My problem is all 3 of my NVMe drives immediately disappeared following the change to enable Intel RST. Even switching back to AHCI, the BIOS does not detect any drives. I have cleared the CMOS, flashed the UEFI to the latest version 1903, loaded the optimized default settings, removed and reseated my drives, and they are not coming back. I thought maybe the UEFI is being buggy and booted up my windows installer to find Windows could not find the drives either. I tried installing windows with RST enabled and I loaded the proper RST driver during install, and I also tried with AHCI but got nothing.
Does anyone have any idea what may have happened here? I tried following Asus’s manual here: https://www.asus.com/us/support/FAQ/1044458/ but my motherboard does not have an Intel VMD section like they outline here for their other products. Not sure what else to try.
Solved partially. Somehow this got reset when enabling intel RST. I have a CPU PCIE configuration mode that needs to be set to pciex16_1 + m.2_1 + m.2_2. It reverted back to only pcie16_1 + pcie16_2 so I overlooked it as PCIe bifurcation settings or whatever. I am still missing one of my other NVMe drives but I’m sure something else got reset in the UEFI too. Now I just need to hunt for it.
