hi,
I have a new Asus PRIME Z790M-PLUS D4 motherboard, and i9-13900T cpu.
If its all put together with a discrete graphic card it boots up fine.
If it take the discrete graphic card out, the built in iGPU does not post. I have reset the c-mos, and still nothing. All i get is 1 long 3 short beeps. The error looks like no iGPU UHD 770 Graphics VGA is supported (there is no signal in HDMI motherboard output).
If anyone has a way to get it working? What could be the problem?
Just a few months ago, another member described the same problem as me, but he had a motherboard Z790 ProArt although curiously the same processor as me, i9 13900t.
This is the thread:

@Extravaganza Finally, did you find a solution?
Thanks in advance,
