Download DirectX 9.0c (redistribuable package) on Microsoft.
The latest is DirectX 9.0c (Decembre 2005)


Open WINNT.SIF and add the command under the GuiRunOnce Section (write if not exist).
In my example, I have extract the package under $OEM$\$$\Temp\directx, but you can keep the package and just add /silent switch after (see next section).
TIPS : ".exe" is optional, so you can write DXSETUP /silent or DXSETUP.EXE /silent, as you want.




Put the DirectX package under \I386\SVCPACK\DIRECTX.EXE
Open svcpack.exe and add this
