It runs since ~6 month fine with proxmox or truenas scale @UEFI with a Dell H310 and without gpu. I wanted to replace the H310 with a HP H240. With this Card installed it stuck at Post with Code 92. I even deactivated CSM, but nothing. Without a GPU it doesn't even beep anymore. Replacing the H240 with the H310 again everything ist fine again

Q79 does not exists? check CPU-Z or HWinfo.
PlexHD X79T use Q77 B75 chipset, the BIOS may not work with other chipset then.

The chipset is a B75. Setting it to PCIe 2.0 didn't solve it.

The problem was: I had to disable " Launch disk controller (or something like that) OpROM Policy". After that it worked like a charm :)
thank you for your help

if you plan to update the BIOS with a one from other boards i.e. PlexHD make first a dump of your current BIOS with a USB programmer(ch341a or similar). i recommend a BIOS which is from a board which uses B75 too. some say different chipset works, some not, personaly i would never use a BIOS from diff.chipset.

Hi,

I got an Atermiter X79 Turbo. Is this Motherboard capable to use UEFI?
Every motherboard can use UEFI, via coreboot for example. All Chinese X79 motherboards have UEFI APTIO 4 firmware. What do you need it for? NVME boot?

What do you use when you need to change things at the BIOS? Some sort of USB video card?
I have several options
- swap the 10g nic with a GPU
- swap the 10g nic with a PCIE expander and connect a GPU with it
- use one of these PCIe 1x --> 16x expander
