you dont need to select any chipset fix or patch because you have extensions.mkext and it has necessary kext in it. What kind of difference are you expecting?

you can look at top of the screen and select apple icon and then "About This mac" >then more info. now you can see the drivers and other things , sometimes SATA drivers shows AHCI name or unknown driver etc.

in fact you dont need to see chipset driver or anything else, just ask your self , how long installation took? 20 minutes? if it is 20 mins , it means mkext is working and your installation is normal duration. maybe more 10 min or less depends on your CPU and HDD.

but not 2 hours!!
