AHCI setting for SSD??

I could use some help here. Before I load my OS I was told to set my BIOS to AHCI for my Intel X25-M 80gb drive. I was able to set AHCI in STORAGE CONFIGURATION (my choices were IDE, RAID, AHCI) and in MARVEL 9123 SATA CONTROLLER (Choices were Disable, IDE, AHCI) but in the J-Micron SATA/PATA controller the only choices were (Disable and IDE).

Do I need to set everything to AHCI or does it matter?

Thanks for the help.

It only really matters for the drive Windows is being installed on, and the controller that drive is using. Windows will load the AHCI driver upon installing if you set the controller to AHCI. If you chose IDE, Windows will load the IDE driver. If down the line you wanted to switch to AHCI after having first picked IDE, Windows will bluescreen upon bootup since it's still trying to use the IDE driver. There's ways around that bluescreen, but AHCI is more beneficial anyway.

Since you're probably using the Intel ICH10r controller, that's the one that matters. You can set the Marvel controller to whatever you want, and you can change it after Windows is installed; Windows will just think it's a new piece of hardware if you switch it, and won't complain at all.

You can disable the J-Micron controller if you don't plan on using its SATA port or the Parallel IDE port. I disabled mine because it kept delaying my boot time since it was loading its own boot bios.

to make sure you are using the good controller, disable the jmicron controller complete while you install windows (if the drive disappears when you disable it, that means you plugged it to the wrong port, switch it to another port). And enable AHCI during windows installation whether you intend to use AHCI later or not (I highly recommend you keep AHCI).
