I've read a whole bunch of posts about IDE, AHCI, Toolbox and trim. What a mess. I can't find head from tail.So many contradictory posts. Are some people giving opinions based on posts they've read.. which might be false to being with!?
Is their some official support forum from Intel where Intel support employees can give authoratative answers or because this is a community forum anything goes? I really don't want to bother with I-am-Not-sure answers. I need definite yes or no.
I would like to see an official FAQ from intel answering the common questions. Such as.. does Trim work on IDE port or not (regardles if I should be using AHCI)
I have seen two visible camps around this question.

The default MS driver works in AHCI mode with both Intel and AMD controllers. (AFAIK)
I'm afraid my knowledge on AMD chipsets is limited. I think I am correct in my posts above but there might be a few complications. I "think" AHCI mode only works in a raid configuration. That might be why the toolbox is not picking up the SSD.
I'm happy to be corrected as my knowledge of AMD is limited.
You might get some more help here:

If you look at one of his previous posts he doesn't even have AHCI working. Best to move on and leave him to it I'd say.

"I "think" AHCI mode only works in a raid configuration". I am not sure what you mean by this. in the BIOS, There are 3 modes for SATA: IDE, AHCI and RAID.
I just want to know if trim is working in my setup, regardless of which driver, motherboard type, or chipset. Is trim a blackbox operation.. you send the command and hope it worked? I mean if I format a disk, I know the disk got formatted. If I delete a file, I know it got deleted and the disk's free space increased.
So what about trim.. how do you measure it or know it did its thing? Unless I can see something visually, I can't know if AMD's driver supports it for sure.

I have asked some questions for you on the xtreme web site, which I linked above. Hopefully someone will answer and give you some definite answers.
There is unfortunately no way of finding out if the TRIM command is being acted on by the SSD.

Thanks. I am not sure what amdsata.sys buys me over msahci.sys. Maybe a little more performance but if it's at the expense of not being able to use trim then I don't want it. amdsata.sys got installed when I installed the drivers for the motheboard. I don't remember if there was an option to include the ahci driver or not.
The installer has an uninstall option but it crashes every time I try it!
Based on http://forums.anandtech.com/showthread.php?t=2083024&page=4 this thread (Anandtech), they recommend not using amdsata.sys. Someone mentioned I can rollback the driver from the device manager so I will try it. I will run AS SSD with and without amdsata.sys and see any performance differences.
Thanks for all the help.
