PATA to SATA - P5k Vista

hello

When I installed Vista i had SATA as PETE/IDE in my BIOS.

Now i want to switch to SATA, i have been playing around a bit not sure if i am having any success.

I have switched the BIOS to "SATA as AHCI" and Vista runs fine, the first time i did this it installed a few drivers.

This is what my Device Manager now looks like

*IDE ATA/ATAPI
-ATA Channel 0
-ATA Channel 0
-ATA Channel 1
-ATA Channel 1
-ATA Channel 4
-ATA Channel 5
-Standard AHCI1.0 Serial ATA Controller (why SATA 1 not 2?)
-Standard Dual Channel PCI IDE Controller

*Storage Controllers
-JMicron jmb36x controller
-Microsoft iSCSI Initiator (no mention of SATA/AHCI here)

Also in device manager my HDD is listed as WDC WD5000AAKS-00TMA0 ATA Device

I have a P5K, ich9 chipset

Am i little confused am i running SATA, how can i check? If I am still in IDE how can i switch to SATA2.

thanks
