Just for information/confirmation your results. I made some tests too with Intel Q270+Core i5-7500 and Q370+Core i5-9500 using CSMWrap 1.2.1 and WinXP SP3 (ntldr). On Q270 system boots OK without external videocard (on iGPU). On Q370 I have black screen without additional external videocard after CSMWrap loaded. With AMD HD6450 and modded VBIOS (GOP module added) WinXP booted OK also. Original HD6450 VBIOS doesn't have GOP so I have black screen too. Video drivers installation not tested yet. For uefiseven I suggest to rename "csmwrap.efi" to "u7.original.efi" for chainload. Or write a shell script. @reboot12 Can you share please your legacy and UEFI "winload" modded files? I try to follow your advises but without success.
