Please see Daniel's post for instruction on how to do that. You should read the Intel section and then follow the instructions on the downloadable document to slipstream all of the drivers. That way you are sure to get the right one.
If you have a USB FDD, you can also extract the above 32 bit Intel drivers to a FDD, hit the F6 key when it asks if you need to install a SATA/RAID driver, and use the up down arrow keys to scroll to and select the specific SATA AHCI driver needed for your model.
If you have any further questions, please don't hesitate to ask.
