Thank you JIm for your reply, i will update the little MAC address customization Wiki accordingly. Just to make sure we are talking about a Prism2 card, runiing under 10.3.3 without any changes applied to the kernel.
Thank you JavaNut too for your post, i am sure it will help users in the future as it is very complete. Any news about "Modrak" SourceForge driver patch for Panther, did you get it to work?
