Hp pavilion dv4-1125nr sata driver

For the last 8 hours I have been trying multiple sata drivers for this laptop in order to load XP on it. They have been one for floppies and ones that have been slip streamed. Does anyone really have a link to a good Sata driver for this model. I am not a newbie, but have not been able to find a Sata driver that will work. Even tried putting in a brand new hard drive. Always get the BSOD. There is no Bios setting to change. A quick reply would be appreciated as a business customer is waiting for this. She has to have XP for her programs to work, they will not work on Vista.
