Can't find driver for unknown device in device manager on T42

Had to reinstall Windows XP on a T42 (2372k3U). Got all drivers loaded but one. Says unknown device on Intel 82801DBM LPC Interface Controller (24cc). What the heck is this thing? I thought I loaded all available drivers. Help.

Re: Can't find driver for unknown device in device manager on T42

Thanks--I was looking for something like that, since it wasn't in the list when I used autodetect or went to the actual model number. BUT--that didn't fix the problem. I'll look some more. Still have the exclamation.

Yeah, I tried that. It didn't find the missing driver either. I just tried some security thing and that seemed to work. I did uninstall the Thinkpad Update utility. Thanks for your suggestions.

Thank  you! This link worked for me and the update resolved the 'unknown' driver in the Device Manager on Win 7 x32.
