Hello Baho U.,


Firmware is normally installed in /boot/modules.

$ grep -e "^KMODDIR=" /usr/ports/Mk/Uses/kmod.mk
KMODDIR=        /boot/modules


$ pkg info -g -l bw\[in\]\*
bwi-firmware-kmod-3.130.20:
        /boot/modules/bwi_v3_ucode.ko
bwn-firmware-kmod-0.1.0:
        /boot/modules/bwn_v4_lp_ucode.ko
        /boot/modules/bwn_v4_ucode.ko

Those were the last versions of the driver installed to my symstem. years ago.


To build a driver for bcm43XX ndisgen(8) is worth a try. If you have not seen it
before, here is a post that gives a quick summary.
