I find 2 sys files for Soundmax Integratd Degital Audio,

If for the same Hardware of another system

I have problem to install Audio driver Or prob to select which INF file.

I have the DRIVERS, facing problem to install manuallay

Tell us a lot more about the machine hardware and where you got these drivers as well as current problemsfor a relevant response. See below.I don't know all the differences between Win 2K and Win XP, and I'm referring to Win XP.  Device Manager shows some info on drivers.  Also, the DirectX Diagnostic Tool, dxdiag, shows some info on drivers.  To run dxdiag, go to Start, Run, and type dxdiag in the Run box.In my computer->PROPERTIES->Device Manager->sound,vidio & game contraller

there Is [size=12]Soundmax Integrated Digital Audio
[/size]

the sys files are aeaudio.sys & smwdm.sys  installed

which is not installed on another system with same Mother board & all h/w

pl help me to configure this driver MANUALLY, & which inf file I have to search?

I suggest you go here and do some reading: SoundMAX Frequently Asked Questions.  Question #2, "Why don't you provide drivers here?", provides links to various computer manufacturer's websites to download drivers.  Question #7 is "How do I install audio drivers?"
