Microsoft System Management Bios Driver

I loaded Microsoft Windows XP Pro on a new system. Everything seemed
to go fine. I loaded all the Windows updates including SP2. After
loading all the updates the system hangs during boot time for
approximately two minutes with a blue screen showing the Windows logo
and the message "Windows is starting up...." While I was trouble
shooting this problem I noticed that there is an item in the System
Devices portion of the Device Manager (Properties of My
Computer>Hardware Tab>Device Manager>System Devices> Microsoft System
Management Bios Driver) that has a yellow circle by it with a black
explanation point of something similar in it. When I clicked on this
item and then on the General tab of the next screen I found the
message "Windows cannot load the Device Driver for this hardware. The
driver may be corrupt or missing.

When I googled the statement about the System management BIOS Driver I
saw some conversation about this causing slow boot up and that this
was only a problem after SP2 was loaded. I am running SP2 on 3 other
machines and have never had this problem nor the slow boot.

Any and all help would be appreciated.
