ok, so, i got a d-link wifi module for my mac g4 with OS X 2.8, all went well and I installed the drivers, but on restart, my mac stalls on start up and a weird black 'block' appears over the apple logo, and thats as far as boot up gets to, I've tried starting it in safe mode but no glory, tried everything else and nothing happens, tried resetting the cuda, nothing happens, and also starting form disk and nothing. The only thing that comes up when i do a keyboard re-start is the firmware configuration page! of course I'm in a total panic at the moment, So, if anyone has any advice, it would be muchly appreciated, this is a much loved machine, so i'd hate to take her to the chop shop...cheers!
