Answers:Windows XP SP3 is fully compatible with the SATA AHCI Mode, but contrary to Vista it doesn't natively have the needed SATA AHCI drivers. So you have to load them during the XP installation (via floppy/F6 method) or - as the better option - to integrate them into the XP-CD. I assume, that you got the BIOS message, because the vendor of your system has preinstalled Vista and is not interested in any support traffic from users, who are not able to get XP installed in AHCI mode (due to missing or wrong AHCI drivers). Regards Fernando Fernando, thanks for your quick response, I will then integrate the AHCI SATA drivers to my Windows XP SP3 to see how it works ... Greetings

Hello, and sorry my bad English. I have Windows XP SP3 and Intel DG965WH motherboard, when I select AHCI mode in BIOS, this gives me a warning ... " Select the AHCI mode only if you use Windows Vista " The BIOS for my motherboard is up to date. My questions are: * Windows XP is not compatible with AHCI mode...? * Because the BIOS gives me this warning...? Thanks...
