Bios Debugging

[Hans Schmid]

General question:
Is there any reasonable way to debug BIOS code. I checked (almost) everything like
AMD's SimNow, Bochs, Qemu, hardware tools like interposers and so on but
they don't fit my expectations/requirements? What I would need were a hardware
based debugger for Intel multicore processors. Any idea?

Kind regards,
Hans :-)

What was missing from these emulators?  SimNow was designed specifically to
develop firmware images.  What did you find lacking?

ICE is unbeatable, but also very expensive.

The American Arium ECM-XDP may be what you are looking for:

About US $12K., so it not cheap.
