Hi - Machine is a PowerBook G3 (Lombard) running with CS 1.2 and a custom
built 2.2.18pre21 kernel. I am trying to set up for a wireless connection
using an Orinoco Silver PC card on the PowerBook (for starters, I am
trying to connect to a machine setup with an Airport Software Base
Station). I have, to the best of my knowledge, followed the directions on
Paul Lucas' site (thanks Paul!) pretty much to the letter. It appears that
things are almost working, but I have run into a problem that I have not
been able to get around.
PCMCIA is working, the appropriate module is loading, and some level of
communication is occurring between the system and the PC card. However,
the logs always report a resource failure (as shown below). I have tried
many different settings in config.opts, but have seen no real change in
behavior. The result is either the output shown at the bottom of this
message or a completely broken config. I have tried excluding no IRQ's,
excluding all IRQ's, explicitly providing an IRQ list, tweaking includes
for memory and ports, etc.
The only way I have found to get around the resource failure is to comment
out the code that performs the check. In this case the card claims to come
up, but reports the following.
index 0x01: Vcc 5.0, irq 0, io 0x0100-0x013f
Are these numbers even valid? They look strange to me, but I don't know
many of the details of Apple hardware. /proc/interrupts doesn't list the
PC card at this point. In this configuration, the log does report a MAC
address on wvlan0, however an attempt to connect results in timeouts
(wvlan_cs: wvlan0 Tx timed out! Resetting card) while waiting for a DHCP
response. All of the above applies both to a configuration using a patched
3.1.22 version of pcmcia-cs and an unpatched version 3.1.26. The wireless
connection does work from Mac OS 9.1.
If anyone has thoughts on where I might have gone wrong, I would really
appreciate the feedback.
Thanks.
Jim
