If that doesn't work, try disabling the jmicron chip (if there's a bios option for that) - and then try switching ports again incase you're now using the jmicron ports.
Failing that, try updating the BIOS, but AHCI has always caused me more trouble than it's worth.
I first tried disabling the jmicron controller. didnt make any difference.
I tryed moving the hard drives to the jmicron controller and then renabling it but didnt work eiether. just had same message "auto detecting AHCI port 3.."
Hello kalniel,
i tryed keeping the jmicron controll set as AHCI and other controller set as IDE but that didnt seem to work eiether. it told me there was no master IDE.
cant remember what i did but the following happerned:
the first hard drive posted but the second hard drive said "auto detecting port 1.. ide" and then stopped even thou its the same make and mode of HD as the first hard drive and on the same controller (jmicron)
