Need help getting AHCI to work

Hey gang, I need help getting AHCI mode to work on my Gigabyte GA-P35-S3L Motherboard. I can enable AHCI in the BIOS but Windows Vista installation doesn't complete for obvious reasons.

I tried to enable AHCI after the Windows Vista installation and it just constantly reboots for obvious reasons. I put the AHCI drivers from my DeLL Vostro 1700 on a USB flash drive. I have to browse the drive on when I want to load the AHCI drivers prior to the Vista install as it doesn't recognize them. When I browse the flash drive and it sees them if I click on the AHCI driver. I get the message saying the AHCI driver is incompatible with my hardware.

Ok so I went to Gigabyte and they don't have any AHCI drivers for my MB. I went to Intel's site and no luck either.

Any ideas how to get it to work? Also will I see an improvement running AHCI over IDE mode? I have three SATA drives and the system sems very fast as it is.

I have a WEI score of 5.3 and the drive transfer rate is around 5.3 which is knocking down my score.

Processor: 5.5
Memory: 5.9
Graphics: 5.9
Gaming Graphics: 5.8
Primary Hard Disk: 5.3

Any ideas would be appreciated.

 

You have to integrate them using vLite.

On how to aquire the ACPI drivers, you have to download the Intel Matrix Storage Manager. Once it's downloaded, go into your command prompt:

Code:

Use one of the following command examples to extract the 
    driver files from the different package types:

      c:\iata_cd.exe -a -a -pc:\<path>
      c:\iata_enu.exe -a -a -pc:\<path>
      c:\setup.exe -a -pc:\<path>

Then the .exe file will start running.. don't worry. Click next and then it will extract the files to the default location you had listed in the command prompt.

There should be several files of which you will integrate into your Vista disc (using vLite or something similar).

Then you should hopefully have a bootable and working Vista OS installation.

 

Install with AHCI disabled. When you finished and boot into Vista, you can enable the AHCI drivers there. Then reboot and enabled the AHCI in the BIOS. You'll get one boot into Vista to install the intel drivers then. Do so and then you'll be finished. The advantage of this is you will have backwards compatibility should you ever need it. Reference my x64 install, the first section of it tells you what to edit in the registry. If you choose not to, just follow the USB instructions. Good Luck.

 

I like your x64 guide-- nice-- you explain about the usb/ahci drivers better than I usually do.........

Thanks! I'll keep up the work!
