This is a simple 200 LOC driver that displays a bitmap on screen after a BSOD occurs.
It uses a modified merge of ReactOS's display.h and bootvid.h to be able to work with bootvid.dll properly.
flopa.mp4
jinx.mp4
Here are instructions on how to build this driver.
Open up the Visual Studio developer prompt, cd to KmdfMandelcheck's root directory, and then run the following command.
lib /def:BOOTVID.def /machine:x64 /out:BOOTVID.lib
Open Visual Studio 2022 and select "Debug x64" or "Release x64". Build the solution, and you will have Mandelcheck.sys in the output folder.
Drop Mandelcheck.sys in your VM and in an elevated command prompt run the following command.
sc create Mandelcheck binPath=C:\Where\The\File\Is\Mandelcheck.sys type=kernel start=auto
Important
This driver will not work under UEFI systems. You must use a VM booted into Legacy BIOS mode.
Open your bitmap file in GIMP, scale/crop it down to 640x480, and make it a 16 color indexed image. Export it as .bmp, and now open it in Paint. Save the image as target.bmp and place it in C:\KmdfMandelcheck\ for the driver to work.
Important
The driver will display a black screen if the bitmap is not 16 color, 4bpp.
Run sc start Mandelcheck in an elevated command prompt and create a BSOD. You can use BSODMachine for an easy way, or you can break and execute .crash in WinDBG. If you are using WinDBG, once a bugcheck occurs, you must enter g to continue execution, otherwise the system will be completely halted.
