I have a SuperServer 6023P-I with Windows 2000 Server and Intel chipset driver installed. However, I still see there are yellow question marks inside device manager under other device section. I removed all cards on the board and still see two of those question marks.
You probably have the old Intel chipset driver installed. Please download the latest driver from http://www.intel.com/support/chipsets/inf and install it again. This should fix the problem.
