Just reset and go. If you close the bsd you'll never see PCI problems of
values that are not cleared on a reset or CMOS problems. Since switching
the BIOS only changes the code the simulation runs, I would have thought it
would be totally safe. If we can't trust that it makes life a lot more
When you press the "log config space" button, do you know where the log
In the log you can see that PCI bus 0 device 6 is initialized, but bus 1
never shows up anywhere. Bus 1 is the PCI bus from the bridge at bus 0 dev
6 as far as I can tell.

I always start with the same bsd, no matter what I'm doing.
