Are you having problems with your network adapter after you wiped vista from your HP 6720s laptop and installed XP?

Does it connect but not grab an IP or won’t seem to allow any traffic to flow if it does manage to get an IP or you set a static one?
Occationally notice that you get an “Error Code 12″ within device manager?

Then the problem is the same as mine, and the solution to it can be found at this address.

Basically, the problem is that you have a BIOS version older than F.03 (09/04/2007) – warning, american date format ;)

Hopefully this should save your hair from becoming bunches in your hands as after a quick flash of the BIOS and all should be right with the world once again ;)
