SeaVGABIOS on iGPU - screen problem
I tested Windows installers from USB on the iGPU card. Older systems may have an acpi problem but this issue is only about the screen problem.
Currently CSMWrap can't use the iGPU's VBIOS so it uses SeaVGABIOS.
- Win11 - not tested, probably works
- Win10 - OK
- Win8.1 - OK
- Win Longhorn 5472 - OK
- Win8 Developer Preview - on screen stay SeaBIOS
- Win7 - on screen stay SeaBIOS
- WinVista - on screen stay SeaBIOS
- WinXP - black screen but after installing WinXP using PCIe graphics card + VBIOS + patched acpi.sys + loader winload.exe Longhorn 5472 OS boot OK or desktop is on top left corner
Summary: SeaVGABIOS + XP, Vista, 7 = screen problem
Yes it's a known limitation due to #3, however you can try to set different resolution with UEFI GOP before launching CSMWrap and sometimes it will work.

I tested on Windows 11. Csmwrap boots on 11 without problems.
Using vbemp driver + UefiSeven to set resolution before run CSMWrap - XP32 works better on iGPU with SeaVGABIOS: https://msfn.org/board/topic/186793-csmwrap-boot-csm-on-uefi-only-systems/page/13/#findComment-1280647

Yes, setting GOP resolution (I use UefiSeven 1.31 fixed by me) before running CSMwrap help use native monitor resolution:
winload.exe 5472 has some problem to display Windows Boot Manager menu and aurora bootscreen but OS (XP32) works OK in native monitor resolution on vbemp driver
Also Win10 (tested 10240) work in native monitor resolution after use small tool app rc.exe
Without UefiSeven Win10 only 1024x768:
U7_noWBM.zip - please set native resolution for your monitor in UefiSeven.ini
The UefiSeven no Windows Boot Manager version also helps you boot Windows 7 on the iGPU card: https://github.com/Gelip/u7nwbm
