I would say that this is a shame. We really need a top-notch full system simulator. But doing complete and correct simulation of chipsets is hard, error prone and quite boring. Therefor emulators like QEMU take the short path, and put in a "phony" BIOS and more or less do not implement a northbridge at all. What we need is a full-system simulator with the following characteristics; * correct, * deterministic, * visible device state, * visible cpu state, * scriptable, * and pluggable (for profiling and coverage tools) Note that I have not put "fast" on the list. I think that is secondary for our use case. ~j
