Any emulator to run IDA (MS-DOS)

[Yuri Grebenkin]

Hi. I like to dig Win32 viruses, and my favourite disassembler is 
InteractiveDisAssembler (IDA) that runs under MS-DOS with extender. But I 
don't like to boot Windows for it. So, please, tell me what emulator 
should I use? I think VMware is too complicated for this purpose, besides 
it's not entirely free. I just need an i386 MS-DOS emulator that can run 
protected mode extender (something like DPMI). I have pcemu, which is only 
i8086, but runs perfectly.

Best regards, Yuri.
