Hi Daniel,
Now I have compiled coreboot 4.5 with the SeaBIOS 1.9.3 as a payload and the VGAbios: I am using the Asus EN8600GT as a videocard (PCIe) and I took out the binary here: https://www.techpowerup.com/vgabios/?architecture=& manufacturer=Asus&model=8600+GT&interface=PCI-E&memType=& memSize=256&since=
Also I have turned on in console settings "Show POST codes...", but there is nothing works:(
You probably also need POST_DEVICE_PCI_PCIE set in your .config. In menuconfig: "Device to send POST codes to" -> "PCI/PCIe".
As for the serial port: I think this mainboard is not a retail version, but came from ASUS Essentio Desktop PC CM1745. http://www.ascendtech.us/asus-f2a85-m-cm1745-dp-motherboard_i_mb90mibiw5g0xb...
Looks like RS232 level translator ICs are also missing and some other differences on BOM too.
