There are FreeBSD loader variables that can be specified to override interrupt specifications apparently provided by the BIOS but without a fair bit of detailed knowledge of the specific hardware design you could spend many hours trying to guess the correct values.

If you want to tinker for a while to see what you can make work, by all means do so. But if you value your time and need to get something working quickly I suggest the Nokia box is not for you.

Since 2.1-RELEASE is right now in the build and final test process, if you wait 24 to 48 hours you might even have a final 2.1-RELEASE image available to try.

Apologies for commenting here…

I couldn't find any post regarding pfSense 2.1 doing a final release. Could you please point me to the right post. Thanks!
