I'm reaching out for assistance with a tricky situation involving 11 Intel-based Wolfvision Cynap units. I've already reset the CMOS battery to access the BIOS and flashed Proxmox onto the drive using a donor chassis (an HP Elite Desk). However, I'm having trouble booting into Proxmox and establishing a LAN connection due to potential hardware restrictions in the BIOS. The video output is limited to HDMI that's routed through a PCIe riser, and I'm not receiving any video signal, which is why I'm trying to connect via the LAN ports. Once I can get a ping from the IP set in the other chassis, I should be able to access it and make updates. I'm seeking guidance on how to move forward from here. Any help would be greatly appreciated!

It sounds like you really need to get that video output sorted first. The issue with setting up on HP hardware is that Proxmox names the network interface based on the specific hardware it detects. If you switch hosts but can't see anything on the screen, you're stuck without a way to change the configuration. You might want to look up the motherboard specifications and see if there's a way to flash a standard BIOS from the manufacturer. Also, could you clarify how that HDMI connection is working through the riser card? Is it just a cable, or is there additional hardware?
Here's a look at the display and capture card connected to the unit, which might help.
It seems odd that even a CMOS reset wouldn't let the unit boot without certain hardware being connected.
Yes, there is a PCIe lane with a riser for all the display outputs. I have a picture of it here.
Do you think that resetting the BIOS with the CMOS could still require certain hardware components to be connected for the boot process?
