Missing driver for Mass Storage controller & PCI Simple Comm Contr

HI,

Each time I boot into build 5384 I am prompted by the New Hardware Wizard to
install the following

Mass Storage Controller
PCI Simple Communication Controller

I've checked my install discs but I can't find these two drivers. Based on
my system specs from DXDiag below, can anyone give me an idea what to try?
