|SATA controller card will come with its driver disc.|
When your OS CD boots there is normally a prompt during set up phase to hit F6 if you wish to load SATA drivers before you fully install the OS.
Once you press F6, the OS install set up programme will note that you wish to add the SATA drivers to the install.
At the appropriate point when required you will be asked to provide the driver floppy to install the driver.
NOTE if you want to install on a SATA drive from the PCI add on card you will also need to update your BIOS settings to indicate this.
The rest should be as normal.
