This box has both NVMe slots populated (01:00.0, 05:00.0), and also the WiFi slot is populated with a small NVMe drive via adapter as the boot drive (04:00.0).

Virtualization tips

Disk controller

Pass Group 25 & 26 directly to the VM — this will cover all 4 drive bays. Drives spin up correctly, spin down when VM shuts down, SMART data works, etc. Tested with TrueNAS.

Ethernet

Group 13 (02:00.0) is the first/rearmost ethernet port (labeled "1" on the case)
Group 14 (03:00.0) is the second/frontmost ethernet port (labeled "2" on the case)

Here is the script used to generate this

If you are going for iGPU aka APU pass-through on Proxmox, here is necessary BIOS and instructions. Use vbios_5825U.bin and install Windows via SeaBIOS (I'm still figuring out how to do this with UEFI)

Important note: passing both SATA controllers (which are onboard the CPU, not discrete) will disable CPU thermal monitoring and throttle the device substantially. See more here: https://forum.proxmox.com/threads/wtr-pro-cpu-throttling.160039/
