drivers not installed

I have an AMD K6-2 400 CPU and when I go into sys.info it tells me that my keyboard, modem,& display drivers are not installed, also the files gendrv.dll and unidrv.dll. The mystery is I’m able to use all of these with no problem,but it bugs me to know that something has to be wrong and I cant find a way to fix it.Running win98 & 5.5 IE. Help Please!!!!?
