Sorry, I think I misunderstood it. I thought the objective of the new_iwi was to get everything in base thus depreciating the installation of net/iwi-firmware-kmod. >> Still, I can not get it working, output from dmesg: >> >> >> iwi0: <Intel(R) PRO/Wireless 2200BG> mem 0xb0107000-0xb0107fff irq 10 >> at device 10.0 on pci6 >> iwi0: Ethernet address: 00:16:6f:93:c9:75 >> >> This appears fine after I load if_iwi no further errors.

First, the iwi_bss module is not loaded automatically if none of the modules firmware, iwi_bss and if_iwi are present, # kldload if_iwi will load firmware, but not iwi_bss. It does not change anything manually loading firmware and/or iwi_bss before if_iwi or loading iwi_bss after, manually configuring iwi0 with ifconfig always causes the error: firmware_get: failed to load firmware image iwi_bss iwi0: could not load firmware I am wondering if this could be caused by the ICH6 bus? I have other problems with the bus, usb does not work although the devices are registered and as mentioned there seem to be a conflict of irq's. I can't find a firmware debug knob, but setting debug.iwi=1 just adds two lines to the dmesg: iwi_newstate: INIT -> INIT flags 0x0 iwi0: timeout waiting for iwi_bss firmware initialization to complete iwi0: could not load boot firmware iwi_bss iwi_newstate: INIT -> INIT flags 0x0 Thanks, Erik -- Ph: +34.666334818 web: http://www.locolomo.org X.509 Certificate:
