Well fuck. I spent all that time modifying the bios, injecting xeon microcode, and turning on and off settings only to find out that my processor (sr00r) just does not work on the motherboard. Fuck you Lenovo. With that said I have a msi motherboard of the same vintage that has all the ports I need. I sent an offer to the seller, now I just need to wait and see if he/she accepts. I just want my pc to go vroom bros :'(
