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
Cheers
It seems that you are using AHCI mode succesfully then. AHCI 1.0 does not mean SATA I.
And the name 'Standard AHCI Controller' suggests that Vista is using its own generic drivers for it.
You should try installing the Intel Storage Manager Software now, it should change the name into
Intel Controller in device managar. Then you can start the software, and check there if your drive
is actually using SATAI or SATAII mode.
