Hi there,Ok. In that case you should at least try to add the device properties what I mentioned above into OC. The memory section is especially important - without it it simply will not boot (along with the agdpmod=pikera - they must be used together). As for b) that is the speed setting of Slot 1 ie. Gen 3/Gen 4 etc. It may come under Max Link Speed under Settings section. As for g) oh it does affect it. Some systems do & don't work with iMacPro1,1, likewise with MacPro20,1 and iMac19,1.
thanks. i'll try. But for info, the system boots, no problem at all. It will boot and load macos. It is just during the POST that there is no video but I know the system is booting.
