I was avoiding EMM386 as much as I could on my slow 386SX25: there was a huge performance hit.
There was the Unreal Mode aka Flat mode. With few lines of assembly code, an memory allocation using HIMEM.SYS, it was possible to access all the memory: the segment limit is 4GB instead of 64KB in this "mode". Of course it was not compatible with Windows, so the unreal mode was more for fun than anything else.
