The CPU is a 13900K
The MSI motherboards have a USB port marked as Flash BIOS, and next to it there is a button marked Flash BIOS Button.
You take the Dasharo ROM file, rename to MSI.ROM, and copy the file to a Windows formatted USB drive. Insert the USB drive into the USB port, and push the button, and the motherboard will turn on and flash the firmware.
The GPU is a 4060, and I only use for AI work loads. The Qubes OS GPU pass-through/gaming guide explains how to do get it working, only using for CUDA compute makes it even easier, it doesn’t require any display to be connected.
