Thanks for the tip. Unfortunately it didn't work - neither forcing the 1394
adapter into compatibility mode, nor forcing all of the adapters in the
bridge into compatibility mode. Incidentally the 1394 adapters are using the
standard XP OHCI drivers. The PCI card in the machine I wanted to use as a
bridge is an Adaptec 4300, the motherboards with the built-in 1394 adapters
use VIA and TI chipsets.
I looked for other information from MS but all I could find were articles
along the lines of "this is how to create a bridge, and it all works, isn't
it marvellous".
Oh well. I've wasted too much time on this already, so I've ordered gigabit
ethernet NICs and hubs instead. It would have been nice to have gotten it
working, especially as it seemed to work okay using ethernet.
