Sorry for re-opening a fairly old thread, but I've got one of these cards myself and I'm having trouble getting it to work with RC11 on my C750. I tried using dvdrw's instructions but get an error message when trying to execute the "prism2_srec -gs wlan0 /usr/local/etc/firmware/pm010102.hex" command and none of the subsequent commands work, and the later posts in this thread regarding getting the card to work in RC11 are too vague to be of any use to me. Has anyone gotten the card to work in RC11 yet and, if so, how did they do it?
Failing that, is there any way that I can still download the RC10 or RC9 ROMs so that I can get it working that way?
