=====================

Rick.  Thanks for piping up.  

The board is an ASUS A7V600 and the contents of /proc/pci are listed 
below.  I have not had a chance to look carefully at this as Bob 
suggested but I thought it might give you the contents of what I've 
stuffed into those pci slots.. <g>

Am I on the right track thinking that I have too many duplicate 
functions.. for the audio, network etc.. and now I have run out of 
standard irq assignments?

Cheers!  Ian.
