Installation of Windows Server 2003 does not recognize the Serial ATA hard disk

I have to install a Windows Server 2003 to a new Dimension 8400. It has an WDC WD1600JD-75HBB0 harddisk on a Intel 82801FB/FBM Ultra ATA Storage Controller & Intel 82801FR SATA AHCI Controller, which was standard from DELL.

When I boot with the installation DVD of Windows Server 2003 the installation program says, that an IDE harddisk was *not* found and the installation aborts. Before I come to this screen I have the possibility to insert a floppy disk with drivers for SCSI controllers or others. I have a floppy disk drive, but no device driver disk with the driver for my serial ata harddisk controller. Where can I find the right driver to put on an empty floppy disk ??? Please help.

Kind regards, Juerg, Switzerland
