Dear Forum I am somewhat confused, being a new member and a novice. I own a Lenovo t43-2668 with windows xp pro installed I tried to put in a wifi mini pci card, but it came up with the 1802 error message saying unauthorizd wifi card install please remove etc Doing some google search research on the matter it seems the issue may be a "bios whitelist" I am thus advised one needs a modified bios. I would like one of these but don't know how to download it or install it. Strangely the mini pci wifi cards I was trying to intall were exactly the same model as the ones being sold at being for the T43 (Phillips 802.11a/b/g) Should any kind soul be available to advise I should be v grateful\ Thank you\ Ian
