Hi, I set up a multi-boot system, XP32 and Vista 64. On XP, I use my hard drive in AHCI mode, but in Vista I couldn't install the drivers for that mode. The Intel Matrix Storage manager setup contains the drivers for the RAID and AHCI mode, but the setup exits with an error if the SATA handling is in IDE mode. On XP, if I set it to RAID mode, I can install the drivers, and on the next boot, when I set it to AHCI mode, it worked fine, but on Vista the system restarts without any warning or error message in the beginning of the system loading screen if the SATA mode is not IDE, so I must install the drivers, but - as I wrote - it don't works in IDE mode. I know that I could install the drivers from a floppy at the beginning of the system installation, but I don't have a floppy drive. I read the driver's readme, and the setup can extract the drivers, but I can't add to the system. In the readme there is an installation method, but I don't understand that. It told that I should make an UNATTEND.TXT file, but it don't tell me what to do with that file. I attach the driver readme to this post. So, I need a description about adding drivers to Vista. Thanks readme.txt
