A few years ago when I first bought it, I installed a Lucent Technologies Prism based mini-pci wifi card in my IBM\/Lenovo Thinkpad X31 laptop because the prism chipset had good linux support.  But, it does not support WPA2 encryption. I decided the easiest fix was to upgrade to an Intel Pro\/Wireless 2100 Lan adapter, which is now supported and works with the wpa_supplicant program to support WPA2 encryption.<\/p>\n

The only problem I ran into durring the procedure was that my laptop BIOS had a "whitelist" of approved cards (those sold by IBM) and when I booted it after installing the new card a warning message came up as follows:<\/p>\n

ERROR<\/strong><\/p>\n

1802: Unauthorized network card is plugged in – Power off and remove the miniPCI network card.<\/strong><\/p>\n

and, the laptop wouldn't boot. (I just LOVE vendor lock in….)<\/p>\n

Luckily, somebody had already figured out how to disable the BIOS whitelist and I found the following program in the Linux Kernel Mailing List archive here: http:\/\/lkml.org\/lkml\/2004\/6\/13\/69<\/p>\n

<\/p>\n

Program to disable the whitelist on an X31 laptop<\/a> <\/p>\n

(Although I had to remove the "foreign" network card to boot into linux and run the fix, it worked just fine, and my Intel PRO\/Wireless 2100 Lan card is working great now. )<\/p>\n","protected":false},"excerpt":{"rendered":"
