A platform discrimination indication register is stored in a wireless
network card. This register holds a platform discrimination indication
that indicates whether the wireless network card can be used to transfer
data with notebook computers or whether the wireless network card is
restricted to transferring data from a personal digital assistant or
defined set of restricted devices. The platform discrimination indication
can be upgraded using a key value obtained from an Internet site. This
key value is limited to a specific wireless network card because of the
use of a unique electronic I.D. An Internet site encrypts the electronic
I.D. to produce the first key, such as a platform activation key (PAK).
This first key is then decrypted at the personal data device in order to
obtain a unique calculated I.D. value. If the calculated I.D. value
matches the electronic I.D. value on the wireless network card, then the
platform discrimination indication is altered (upgraded), allowing the
operation of the wireless network card with notebook computers.
