Description

I have used latest git version of coreboot to build a rom for my ASUS P5QL-EM.
I have some strange behavior:

I use a X16 nvme Adapter in the X16 graphic card slot. I also want to use an add-on gpu card (nvidia GT710 PCIe X1) to be able to use higher resolution displays.

With the bare board without any card everything works fine, but when I plug in the nvme adapter card with ssd, only the VGA output is working, but it is shiftet one character to the left. HDMI and DVI output are dead. It is possible to boot from the nvme ssd in this configuration. When the GT710 is pluged in, it is no longer possible to boot from the nvme ssd. (Read Error)

Can you provide a coreboot log: either capture it from serial or try to boot from a different port and use util/cbmem to fetch it from memory?

My version of the board is missing the serial port connector. I will try to solder one onto the board to provide the logs.
Is there a documentation how to boot form a different port and use cbmem?

Here is the log from the serial console. Nvme in PCIe X16 Slot and not Signal on HDMI Port. VGA Port is working
