At least there is some advantage there.
You can tell us who brings a bios up first :)
One of these days I'll have to try a post card and see how useful
it is for debugging. I'm pretty certain a serial port works better
in the normal case.

Hmm. I'd have to see the specs to really believe it. Last I checked
the interface for flash chips was directly connected to the ISA or LPC
bus. Of course the implementation can be so simple that you can't
support anything else.
