1) Make sure AHCI is not enabled in your BIOS, otherwise this guide is pointless for you.
2) Open \\PREPARE\IMSM_PRE.inf in Notepad.
3) Replace any instance of XXXX with the following, according to your southbridge:

* ICH6M - 82801FBM (Mobile) -> 2653
* ICH7R/DH - 82801GR/GH Serial ATA AHCI Controller -> 27c1
* ICH7M (ICH7-M Mobile Family) Serial ATA AHCI Controller -> 27c5
* ICH8R Intel(R) ICH8 Serial ATA AHCI Controller -> 2821
* ICH8M (ICH8-M Mobile Family) Serial ATA AHCI Controller -> 2829
* ICH9R Intel(R) ICH9 Serial ATA AHCI Controller -> 2922
* ESB2 - Intel(R) 631xESB/6321ESB Serial ATA AHCI Controller -> 2681
* EP 80579 - Intel(R) EP 80579 SATA AHCI Controller -> 5029

4) Save the file and close Notepad.
5) Run INSTALL.CMD in PREPARE directory.
1) Enable AHCI in your BIOS and save.
6) Start Windows XP, The Found New Hardware wizard will start automatically.
7) Click Cancel
8) Download latest Intel� Matrix Storage Manager from http://www.intel.com/support/chipsets/imsm/
9) Go to Intel Matrix Storage Manager directory and run Setup.exe
10) Reboot windows and enjoy.
