I am confused! Are you saying that I booted XP x64 with 4GB Decoding enabled on UEFI Class 3 laptop through CSMWrap?! Btw, did the PAE patches (that you have, from XP2ESD, I believe) do nothing for XP x86 using CSMWrap?

@Dietmar Just so you know. I also used CSMWrap on my UEFI Class 3 laptop ASUS x509FA, and so far I have no issues with booting XP x64 on UEFI Class 3 using CSMWrap (partitions set at MBR) at all (just like Gelip/Reboot12 said, with CSMWrap graphics don't show at all on ntldr for me, but on winload.exe with vbemp, I can see the display). I have no option for 4G decoding, and it isn't even specified in CSMWrap's log for my case (so I guess it's always disabled in my laptop). The assumption that CSMWrap needs CSM to boot isn't true because you need to explain how it works without problems in my case (on my Windows 11 UEFI Class 3 laptop that has no CSM at all). I hope you debugged the problems related to CSMWrap and sent them to FlyGoat on GitHub.

By errors I can also mean things not working they way they should like the display freezing but the OS still loading. Btw, I am only talking about XP x64 on UEFI x64.

@reboot12 Regarding your solution of always using vga.sys at first deployment, you can also change the service in your video driver by changing the Service string to the name of VgaSave from Vga inside the enum key, to the key that matches that hardware ID of the driver (change permissions in the Enum key to edit the contents inside the Enum key). If the installation of any driver has removed the service needed by that driver (due to inf errors etc), the keys can be added to the key matching your hardware ID (assuming that the service was present but didn't integrate properly in the driver's enumeration entry) to prevent future errors in the respective driver (as you see in your enum key, the keys match the hardware IDs of the driver you're looking for). For example, I use vbemp legacy vga driver (as the VgaSave service instead of the ms vgasave) and it's always loaded on the device manager without errors. I disabled pnp vbemp (to prevent delay at bootscreen) and I used only the non-pnp vbemp driver that is named vga.sys.

I don't understand why I kept receiving infinite boot delay with this acpi.sys. The problem was fixed after using the previous acpi.sys that I had used.

Thank you so much!

@Mov AX, 0xDEAD @Dietmar Can you guys please give me the download link of the latest V8 WIP 2.0 acpi.sys that you have?

Btw I realized that in the vgapnp.sys and VGA.sys windows 7 generic drivers, they're still the same because the vgapnp.sys (from win 7) I have for XP has vga.sys as internal filename and has same size as the vga.sys file.

Instead of deleting the display.inf file, rename it to display.inf.old to prevent the installation. I prefer methods that only disable and do not remove the files and services in case of problems (for backup purposes).

Thank you for adding StartAllBack Canary, the system tray is back!

@Dietmar I would like to know how to debug individual drivers (sys files etc) on the same computer. How do you do it?

@Mov AX, 0xDEAD Is there a problem with the upcoming workarounds for ACPI 2.0? Is that why are you delaying?

Oh, that's terrible. How can this be fixed in Canary?

@Tihiy This bug isn't supposed to happen... What happened to the system tray and the clock, why it's gone? When I disable StartAllBack's taskbar, the system tray and the clock show from Windows 11's default taskbar. When I try to use the start menu's search bar, the screen is covered in the Mica effect, as shown in the second screenshot. Please fix this! I am using Windows 11 25931.1000 Insider Preview.

@Mov AX, 0xDEAD@Dietmar Can you please tell me the current progress of the ACPI 2.0 driver?
