Voodoo mode is the ultimate test. Imagine having access to 4GB of memory from real mode.

Shameless plug for my https://blogsystem5.substack.com/p/beyond-the-1-mb-barrier-i... article from a couple of years ago. You'll find a deep dive on unreal mode (I just learned it's also known as "vodoo mode") and some hands-on code to play with it ;-P

There are things like DOS4GW that you can use as loaders.

I want vooDOS 5.0 which is 32 bit clean :)

Most people called it unreal mode.

Yep. The microcode in real mode segment loading (as shown in the post) does not set the limit to 64KB. That is why returning to real mode with a large value like 4GB in limit gives you "unreal mode".
