80386 real mode simulator

I am looking for 80386 real mode simulator, can you recommend some? I am interested just in CPU core and memory, I dont need peripherals and accurate modeling of instruction execution time due to pipelining. I have already briefly tried simulator included in dosbox but didnt like开发者_Go百科d its UI much. Thanks.

What specifically are you looking for? Any x86 simulator will load the bootloader in real mode. qemu and bochs are both free and can emulate x86 processors.

There is also dosbox, also with its own debugger.
