Backporting the Microsoft Basic Display Adapter driver from Windows 8 Build 7963 to Windows 7

[Chuterix]

From MyDigitalLife.net. The original topic can be found here

By backporting the generic display driver from Windows 8 build 7963 (a beta which has both x86 and x64 builds), in which it can support both UEFI GOP and Legacy VGA BIOS, the benefits of the generic driver can work in Windows 7 and UEFI class 3 systems that can't support UefiSeven can receive display output.

Even if the driver files fail and nothing actually happens, we can backport some display miniport drivers from build 7963 too.

What we need is to fix/mod the .inf file. Here are the results with vanilla driver:

The .inf fix/mod hasn't been done yet; please discuss here.

Then for the internal modding:

Original watchdog.sys doesn't work; we need the one from Build 7963, in which we will change the file to link to build 7963's watchdog.sys by renaming it watchdog8.sys and changing the import.

Missing import in ntoskrnl.exe found; we must use ntoskrn8.sys (NTOSKRNL_Emu, found here [fork]) to fix this.

Before:

After:

No missing imports found (AFAIK).

WIP Files (x86 not verified real imports, also .inf needs to get fixed if it's possible).
