Thanks for the suggestions to use arp and firewire!
Now I am wondering about symbols. I'll do some reading, but while I'm
getting to that point, I thought I would ask.
How does one get symbols setup for debugging at boot time?
Normally, I use kextload -s to generate the symbol names. Obviously I
can't do that at boot time.
Thanks for your expertise,
...Duane
ps
This is probably in a document somewhere that I just need to find and re-read.
