1. Download the drivers for your motherboard SATA controller, or locate them from the motherboard driver CD-ROM.
2. Copy the driver files to a floppy.
3. Boot the Windows XP Installation.
4. When prompted hit F6 to install additional drivers. The installation will read floppy in A: for the drivers.
5. Select the correct driver (often you have couple of different options to choose from, say 2000, XP 32bit, XP 64bit) and hit enter.
6. Continue the installation process as usual. Leave the floppy into the A: drive (the installation will copy the files couple of times)
