Slipping SP3 into Windows XP Media Center Edition 2005

Hi

I am running Windows XP Media Center Edition 2005 on a HTPC. I have a SATA
hard drive in my system as C:
When I installed it the first time, I had to insert the SATA controller
driver during installation by pressing F6 at the beginning.
The question is:
If I slip in SP3 and makes a new installation disc, will I still need to
insert the SATA driver manually during installation? Or are those drivers
included in SP3? Another option is to insert the SATA driver with nLite, but
will that automaticly install the SATA driver during installation?
