I have an older system with SATA I ports and in the Bios I can only choose IDE or Raid mode. No AHCI mode.

I bought the card so I could hook up a Crucial SATA III 128GB SSD and transfer my WinXP SP2  system hard-drive over to it and use the SSD as my boot drive.

I installed the card into a PCI X V2 slot and installed the software with no problems. Connected up the SSD and used cloning software to transfer the HDD to the SSD. Works fine except that the speeds are not great but are about three time faster than my old HDD.

At boot up I see the screen for the card where it says it is in AHCI mode and it sees the SSD as a SATA III device.

Even though at boot it says that it is in AHCI mode is it really? Is there anyway to check if it is running the SSD in AHCI mode?

When WinXP was originally install there was no need to have AHCI drivers because the motherboard doesn't have that mode.

My question is, if I was to do a clean install of WinXP and was to install the cards drivers using F6 to load them during the install process, do the drivers include AHCI mode drivers and would the card then be run in AHCI mode?

Hey JP,

You are correct. If you do a clean install, and If all goes well the card should run in AHCI mode.

Thanks for the reply Tech_UTT,

My confusion is that if these are the same drivers that I would use on a clean install, what is the difference between installing them now with an existing install of WinXP? Shouldn't it be working in AHCI mode now?

Have you try it? What happened?
