Reflashing Orinoco MAC Address

03-24-2002

Hi, I'm new and was wondering if it is possible to reflash a Dell TrueMobile 1150 to be a normal Orinoco Gold with a custom MAC address in firmware that duplicates my Powerbook's Airport card?

I don't know about flashing the card, but the MAC address can be edited in windows registry. Just do a search in the registry for NetworkAddress. You should only find a handful of keys. Find out which one is related to your card, and edit it to whichever mac address you would like. This will only work until the next restart however, at which time you'll have to re-enter the new address.

Supposedly, with older drivers and firmware, an option is available directly through the driver for the ORiNOCO cards that allow you to edit the MAC to any desired value. That seems to have been done away with in the more recent revisions however.

No matter, I wrote a small app that creates a random MAC address and sets it accordingly in the registry. You then must stop and restart your wireless card, and an ipconfig /all will show you that you're using the new MAC address. I'm in the process of figuring out how to use this to change my MAC at boot, without any intervention. I guess I'll probably post back here if/when I figure it out.

That answer your question? heh.
