You probably need to figure out a way to either build new media that includes SP2 in the install disk, or 'find' SBS media with SP2 pre-integrated.

Some of the newer PCs just can't be installed with anything less than SP1 and some even have to have SP2 to be able to install any version of 2003.

First, BOTH the PERC 6 drivers and the SBUU (Dell installation utility) require SP2, so you will at minimum need to create an nLite CD with SP2.

This is the driver you should be using, extracted to floppy (or to a folder for nLite integration):

You can also use the SMTD (System Management Tools and Documentation) DVD that came with the T410 to install the OS, but keep in mind, you will still need an SP2 media.

Thank You very much!

I added the RAID driver via Floppy and the T410 started the installation of setting windows.

After a while, the windows' setup prompted me to load RAID drvier pxxxx.sys from CD. WoW!!! I had it on Floppy but not on CD. So I inserted the driver into the SP2 CD again and it continued a run without issues anymore.

I have the Windows SBS 2003 SP2 running on T410 now.

It is cool.
