I just bought a new ssd, and wanted to run it in ahci mode, but either a.) my motherboard doesnt support that, or b.) i don't know what i am looking for in the bios. I suspect the motherboard doesn't support it, even though it uses the ich9 south bridge, which supposedly does support it. If anyone has any help or advice on where to look for this info, it would be very helpful.

Thanks.

I just downloaded your motherboard manual and did a quick review. I couldn't find where it supports AHCI within the manual. You can download it yourself for another review at http://www.biostar.com.tw/app/en/mb/content.php?S_ID=29... but it looks like you'll need to run in in IDE mode.

is that going to be a major problem? will it bottleneck the speed or anything?

In the BIOS it is under Drive Configuration. The ATA Mode should be native A and the configure SATA should be ACHI not RAID or IDE. What OS are you running, for Windows XP you need to load the ACHI drivers from a floppy in the OS install by hitting the F6 key. The drivers can be loaded after OS install under Windows XP see this post: http://forum.msi.com.tw/index.php?topic=106575.0. For VISTA and Windows 7, you can load the ACHI drivers from a USB thumb drive on the install.

I am running windows 7. Even if i attempt to install drivers for ahci, if my motherboard doesn't have the option to enable it now, it won't do me any good, correct?

If I were to install something like this:

would it allow me to use ahci even though my motherboard bios does not have the option for it?

Just wondering if you ever resolved this situation. I'm working with the same motherboard and am considering adding an SSD. Were you able to make the configuration changes in the BIOS?
