Once you have the firmware image, you 26 will need to place it in /lib/firmware. 27 28 You will also very likely need the Wireless Tools in order to 29 configure your card: 30 31 <http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>. 32 33 It is recommended that you compile this driver as a module (M) 34 rather than built-in (Y). This driver requires firmware at device 35 initialization time, and when built-in this typically happens 36 before the filesystem is accessible (hence firmware will be 37 unavailable and initialization will fail). If you do choose to build 38 this driver into your kernel image, you can avoid this problem by 39 including the firmware and a firmware loader in an initramfs. 40 41config IPW2100_MONITOR 42 bool "Enable promiscuous mode" 43 depends on IPW2100 44 ---help--- 45 Enables promiscuous/monitor mode support for the ipw2100 driver. 46 With this feature compiled into the driver, you can switch to 47 promiscuous mode via the Wireless Tool's Monitor mode.
