I try to make my wlan card with chipset TI acx111 work under Slackware 10.1 with kernel 188.8.131.52. The instructions say that I must install the firmware, a file with extension .bin_184.108.40.206, in /lib/firmware. When I try to run that binary, I get the error 'Cannot execute binary file'. I have given it executable permission. What does this mean?
