Probably you know that HP "whitelists" certain WiFi cards to work with their systems. It does this by comparing the Vendor ID, Device ID, and SubSystem ID of the inserted card to the ones listed in the BIOS. This is a major problem if you run OSX on your HP as you know the supported WiFi devices are a bit limited under this OS. If your HP shipped with an unsupported card (Intel 3945 for example) you will have to buy (a rather expensive) HP branded replacement in order to make it work. TTAV134 at My Digital Life Forums has released a number of bioses for HP laptops in which the whitelist check routine has been bypassed allowing us to install any WiFi cards (even Apple ones) without problems. This bioses also includes a SLIC2.1 tables for Windows 7. I've added a bios flashing package (machines with Intel x3100 graphics only!) with detailed instructions to the downloads. USE IT AT YOUR OWN RISK!
