3Com 3CRWE62092B Wireless NIC

[pvdbor]

I'm using Knoppix 3.2-2003-03-30 and whenever I insert my wireless 3Com 3CRWE62092B wireless pcmcia nic into my laptop, it gets detected by cardmgr (as it should) and then my system freezes!

The odd thing is that I can unplug the card and the system unfreezes again!

Any help would be appreciated.

Regards,
Peter

Does Knoppix boot with the card already installed? Have you disable PnP in the BIOS?

If none of those work and it freezes your system perhaps you boot windows, have a look at what IRQ it gets assigned and then boot Knoppix and do a

cat /proc/pci

to see what IRQ's are in use. If for example your NIC in WIN was IRQ8 and IRQ8 shows as "in use" for Knoppix then it's likely that you're having IRQ conflicts. Perhaps booting like this would help:

boot: knoppix pci=biosirq

and of course use any other cheat codes that you normally use.

Hi,

Thanks for the tip.
Unfortunately to no avail.
My machine doesn't boot with the card inserted.
It gets to starting the cardmrg and then "waits" until I unplug the card again. (and then it happily boots on)
Output below.

I've also had a look at IRQs, but my card uses IRQ7 and when I look at the PCI IRQs in use, they're all at 11 except one at 9.

BTW. My laptop is an IBM Thinkpad 600X.

OK - did you disable PnP in your BIOS?

Also you may have the option to disable the automatic assignment of IRQ's in the BIOS, if so disable it as well.

Unfortunately the Thinkpad BIOS does not have the options to disable PnP.
Actually the BIOS of my laptop doesn't allow for any modification except the very basic such as boot order.

I found this:http://www.io.com/~manojk/linux-tp600x/
It seems to have some relevant information. Look at the section titled 'PCI Bus Power Management'. Hopefully this is of some help.
