That information is hard coded into the device. I do not know why the Thinkpad's BIOS did not flag the card as illegal on the initial startup. My HP certainly does. I think that "whitelisting" the wifi cards is a horrible practice. I have used HP notebook computers for about 10 years, but the current one will be the last due to their BIOS practices. I own 14 mini-PCIe wifi devices, and only 2 are whitelisted. Similarly, I will never buy a Lenovo notebook. I use these "foreign" PCIe cards on an ExpressCard extender card, but that came from Realtek as part of my work with them. I do not know of a source for these cards. Larry
