Imagine someone could actually help me here....

I have formatted my hard drive, fdisk'd and fully partioned 4gb HDD with dos.
Trying to run games..... all good.
No sound.
PC is old, 380mHz IBM aptiva
On board audio

How can I load drivers etc to get some sound???
I can't identify the name of the motherboard or anything else that helps, is there some way to find out via DOS? Is there a standard set of drivers that can be loaded to get basic sound?

Had audio before format (winxp) so i know hardware is ok.

Have been searching for many nights now, so any info would be of great assistance.

Thanks
