UefiSeven: Easily boot Windows 7 on UEFI class 3 devices

@Gelip You can see in commit nothing more was touched, just added support for dynamic resolution “hack” through INI instead hardcoded one. Results should be same..

But build environment was changed, that could be cause

 

@George King
Yes, I noticed it:

Strange that UefiSeven 1.31 works differently than 1.30

 

I think where could be this issue. Are you able to set build environment?

 

I successfully compile version 1.24 on Ubuntu 16.04.6 LTS

U7 1.30 has a changed code and not work on same OS . I tried use UefiSeven.c from 1.30 in sources 1.24 but compilation errors.
Compiling 1.24 is simple - after downloading source uefiseven-1.24.tar.gz just to do:

Code:

tar -xvf 1.24.tar.gz
mv uefiseven-1.24 MyWorkspace
cd MyWorkspace
make -C BaseTools
. edksetup.sh
build -a X64 -t GCC49 -b RELEASE -p MdeModulePkg/MdeModulePkg.dsc

and after about 8 minutes I have compiled UefiSeven

U7 1.30 need edk2 source and brotli submodule source. I tried git clone but errors, I tried manually download and unpack brotli-1.1.0.tar.gz to BaseTools\Source\C\BrotliCompress\brotli
but still compile errors

 

What build error(s) did you get? I might be able to help.

 

I'll try to build the 1.24 version and backport any patches (without upgrading the edk2 repo) that has been made to the repo after 1.24 to see if it still has the bugs when i got the time to do so.

Yea, U7 1.31 and set other res than 1024x768 in UefiSeven.ini only makes sense if we also patch bootmgfw.efi or winload.efi because with any other resolution not work because bootmgfw.efi (bootx64.original.efi) switch back to 1024x768

But my compiled version 1.31 work OK if set default 1024x768 in UefiSeven.ini

thank you for this correct clarification

I wonder what are the differencies of an (actual) disabled CSM UEFI system to an UEFI Class3 system.

there are cases that talk about CSM not fully disabled on some systems that offer CSM even when disabled in bios and that you may also have to enable fast boot etc.

in my case, when booted with CSM disabled, win7 display output is frozen on the win dimming logo

 

Pure uefi = class 3

Uefi / csm uefi 2 ...

I installed Ubuntu 16.04.6 LTS server once again. OS is already pre-installed python 3.5 but old python is needed for BaseTools compile. This is a minimal list of things that need to be installed to build UefiSeven 1.31:

Code:

apt-get update
apt-get install build-essential uuid-dev iasl nasm tofrodos python p7zip-full

I edited also post #507

 

Practically, I haven't yet seen a working edition of win7 on a class 3 device. Going to try to look for the pre release builds of win8 which mostly look like 7 and see which ones work.
