Firewire on B+W G3 Rev1

[Norberto Quintanar]

I once tried to install a non-OHCI firewire card in my YDL box.  If
someone asked me to do it again, I would immediately  make an
appointment that day with the dentist for the root cananl I've been
putting off.  It's not worth it, because even if you finally get it
recognized, most of what you'll plug into it won't recognize it.  So
you'll still be SOL.  Do yourself a favor, get an OHCI compliant
card.  Here's a link to explain all the headaches and what nots...
