amd FX/A6 unable to boot modern OSes

[ProjectPatatoe]

I've been running into an issue where older AMD parts have been completely unable to boot OSes and am wondering if there is a bios setting, AMD bug, or maybe even not AMD related issue. I can only really test AMD since that is what I have around.

 

Case 1:

AMD FX6350

Dont remember motherboard

Friend wants to install windows 10 from USB to SSD. Installer hangs during install and will never complete. Various combinations of UEFI/Legacy, GPT/MBR, IOMMU tried. Using IDE mode and Legacy boot got me the furthest progress but would still randomly freeze. Ubuntu/Manjaro on USB would not boot. Solution was to install Windows 10 using a different computer, then move the drive over.

 

-Present day-

Goal: trying to install OPNsense(vga image)

 

Case 2:

AMD a4-7400k

Asrock A88M-G/3.1

Tried to boot OPNsense, hard reset. all default settings

 

Case 3:

System that is currently plugged in

AMD A6-6400k

Gigabyte F2A58M-HD2

Tried to boot OPNsense, could not boot. all default settings.

Using OPNsense safe mode, able to get to installer, hard resets when configuring drives to install on.

Tried to boot Manjaro, hard reset about 3 seconds upon reaching the desktop.

Tried various combinations of no ssd, IDE/RAID/AHCI, IOMMU, HPET, Legacy/UEFI

 

 

Any ideas?

busted PSU, still issues with the Asrock A88M-G/3.1 consistently POSTing as it seems to be mishandling the Supermicro NIC but problem solved
