Doubt that you will find any 2003 drivers. You could try an XP driver and see if that works. Other than that, 2003 most likely wouldn't work on that system.

You can also try Intel's site. As the 330 has an Intel G31 chipset

you can look for a Windows 2003 chipset/SATA driver on Intel's site and see how far that gets you.

Post attempt #3

Tried it and it won't run in 2003. Thanks for the help.

I had the same issue today 1/28/09 while trying to installed Windows 2003 Server R2 on a Dell OptiPlex 330.  There is a setting in the Bios that changes the HD controller to operate as ATA.  

Here's How:

Enter BIOS --> Drivers --> Sata Operation change from "RAID Autodetect / AHCI" TO "RAID Autodetect / ATA". Don't forget to save your changes.  Making that change worked for me.  I tried returning the BIOS setting to the original configuration, but the PC kept rebooting after doing so.  I changed it back and all is well.

I hope that helps someone.

Would it be possible to switch the mode of operation back to "RAID Autodetect / AHCI"after installing the SATA drivers in Windows?

I have never been able to switch back to AHCI mode, even if I install the drivers.  The only way I know is to get the drivers press f6 I think during installation and load sata drivers, then install.

I installed last night using the above method, switch to ATA mode.
