None Asus P3B-F and Ricoh RL5C475 - mixed irq ?

I did a little more checking and I now believe that the problem is not
with the ThinkPad - it is with the router box on the other card. Maybe
rename this thread

The router box is a generic PIII machine, Asus p3b-f motherboard (6 pci
variant) and the pcmcia adapter is a Ricoh RL5C475 in slot 2 (slot 2 has
a dedicated irq).

When I boot the router (rh 6.2, pcmcia 3.1.13 with debug up at #3) I get
the following message:

card insertion gives me:

wvlan_cs: hcf_action(HCF_ACT_INT_OFF) returned 0x0
wvlan_cs: hcf_action(HCF_ACT_CARD_OUT) returned 0x0

my config.opts file is:

## begin
include port 0x100-0x4ff, port 0x1000-0x17ff
include memory 0xc0000-0xfffff
include memory 0xa0000000-0xa0ffffff, memory 0x60000000-0x60ffffff
include port 0xa00-0xaff
exclude irq 4
exclude irq 3
exclude irq 7
exclude irq 12
## end

I have no options for loading the i82365 module. When I cat out
/proc/interrupts, irq 9 is not in the list.

Perhaps the cause of the problems is the irq routing (00:04.2 -> irq 9
in boot message). What is this likely to be and how do I go about
disabling it - irq is not listed in /proc/interrupts (and not shown at
the post-bios pre-boot screen).

When I flip into windows 98 and setup the same network informatation
( I can ping between the cards - everything works - apart
from the choice of OS. Looking at the properties of the card gives me a
port range of 0x1000-0x103f, an irq of 9, and a memory slice of

Please let me know if I need to give more information to work this one
