PCI serial controller on bootup

I recently blew away win2000 on my puter because it was not compat. with my audio software card, etc…

I did a complete install of win98 ver2. I installed all my cards again. But I still get looking for PCI serial controller message, and ask to install. I cannot find where to get it. I looked on all the CDs that came with my computer and on the win98 install CD.

Can someone tell me how and where to get this controller?
