Hello Warner,

> Ok.  I'll do my best to describe it. 

Thank you. Your description did make things a lot clearer and I now have
a much better understanding of the new scheme. My previous exposure to
PCMCIA has only been on StrongARM CPUs, and the controller was built
into the CPU so these PCI bridge solutions are a bit new for me ;-)

This, followed by powering down the card and then back up using pccardc
worked a treat. Looking at the code, I have modified the initialisation
of mem_start in pccard_nbk.c to be 0xd0000 instead of IOM_BEGIN for now.
I then removed these lines from my loader.conf file and the card comes
up perfectly:

hw.pcic.intr_path="1"
hw.pcic.irq="0"
 
Thanks for the help, and the explanation, much appreciated,

John...
