You almost answered my question a little...I also have one of these IBM cards...and yes it has the external ant. conn....but what I was wanting, is hopefully you can give a little more detail on how you can update these cards w/ the Orinoco firmware, drivers, etc...and and all information would be greatly appreciated...you did a fine job with what you have given thus far, but if you could make a little bit more detailed write up that would be GREAT!!!
