hi,

To all those finished packing more boxes..:)

problem solved. You were right, seemingly an irq conflict.

But I would like to learn something. What solved the problem in the end 
was a BIOS setting whereby for PCI slot 3 (the slot I had the card in) 
the IRQ PRIORITY was set to "Auto".

I selected "3" for the IRQ priority (top of the list and I was in 
trial-&-Error mode) which sorted the problem.

Now what IRQ numbers are used by rtnet, what is the irq "priority" and 
why-oh-why would the PC generate a conflict of its own accord if left to 
select the IRQ priority automatically?

This will help me understand such issues in the future.

TiA

Kind regards,

Roland
