Hello, I am hoping someone could help me. I changed my case with all the same components to a new case, was having issues getting POST until I cleared out CMOS. In my bios I have SR-IOV, VT-d, "Above 4G Decoding" all enabled. (I do not see "IOMMU" keyword anywhere on my bios so I assume it's on by default or it's an AMD thing, sorry if I sound stupid (I have intel)). Specs Unraid Version: 6.11.5 MOBO - ASRock Z490 Pro4 CPU - i7 10700k 64Gigs Ram 3200 Corsair Primary GPU (top/first slot PCIe) - EGVA GTX 1060 Secondary GPU - GTX 1660 - I troubleshooted using multiple and same cards. It's just the Primary/First PCIE that doesn't wanna do anything but give me Code 43, I have installed multiple VMs, with the latest drivers straight from Nvidia, and for kicks and giggles from the Windows Update. In the second PCIE Slot (doesn't matter the GPU) it works fine, there is no physical damage on the cards and or Primary PCIE slot either (Unraid see's the card, I am able to get a display upon boot). I followed a few guides Tutorial 1, Tutorial 2. I never needed a VBIOS on any of my cards, but I figured it's worth a shot. So I followed "Spaceinvader One" video How to Easily Dump the vBios from any GPU for Passthrough, along with his Userscript Dump GPU vBIOS, no luck with my VBIOS so I download others from Tech Power Up - Video BIOS Collection. Added additional flags/strings to my "Syslinux Configuration" default menu.c32 menu title Lime Technology, Inc. prompt 0 timeout 50 label Unraid OS menu default kernel /bzimage append vfio-pci.ids=10de:1c03,10de:10f1 pcie_acs_override=downstream,multifunction vfio_iommu_type1.allow_unsafe_interrupts=1 initrd=/bzroot label Unraid OS GUI Mode kernel /bzimage append pcie_acs_override=downstream,multifunction initrd=/bzroot,/bzroot-gui earlymodules=vfio-pci video=efifb:off,vesafb:off vfio_iommu_type1.allow_unsafe_interrupts=1 gfxpayload=text label Unraid OS Safe Mode (no plugins, no GUI) kernel /bzimage append initrd=/bzroot unraidsafemode label Unraid OS GUI Safe Mode (no plugins) kernel /bzimage append initrd=/bzroot,/bzroot-gui unraidsafemode label Memtest86+ kernel /memtest Also defaulted them back to how it original was... I am just at a loss, and I really could use a hand. Thank you in advanced, I am not sure what y'all need but I've attached my current .XML VM, System Diagnostics, and VFIO IOMMU Grouping thingy below. P.S. I also reformatted my Unraid USB OS to straight fresh, and re-did everything with still no luck. tower-diagnostics-20230511-1346.zip VM XML Template.txt
