P5AD-2 Premium unknown device after 1005 BIOS!

I upgraded to the latest BIOS today, and suddenly I have an unknown device, placement: 82801FB LPC Interface Controller.

I think it's part of one of the bridges, but installing the latest INF from Intel didn't do anything for me. Any help would be appreciated.

Slightly embarassing... Putting in the CD that came with the mobo fixed it. It never occured to me before I found the soludion for another mobo, since the drivers on a CD usually are outdated before the board is in the shop!

Happens to me all the time. I search for something before I actually use the CD that came with it initially.
