Undefined Multi Media device

Hello all
After installing win98 on a
PII 266Mhz 128Mb Win98 SP 1
Device Manager shows yellow !
over multi media device and
ms diag show it as problem
device (undfined or unknown
driver not loaded). I then
realized that I did not have the
speakers hooked to the card
during setup. Anyone know if
this could have caused setup
to ignore the card.
Thanks
