Simulator for x486

Hello,

I am working at a boot loader for a x486 CPU. The CPU starts from Flash in 8086 real mode initializes the GDT, jumps to protected mode and sets up the chip set, DRAM controller etc.

Is there any simulator where I can single step the opcodes out of the flash rom image? Host operating system ist Windows XP, Linux would be possible but harder to set up.
