I just updated to 12.1 have some AHCI issues bsod etc  , but before updating catalyst I enabled AHCI in bios and win reg. I am convinced i saw some AHCI drivers mabe windows drivers  in device manager, but now they are gone. Am I looking in the right place for the  AHCI drivers and how do I know if I am actually running in AHCI mode ? 

I also updated the chipsset with version 12.1  and is there not suppose to be some AMD AHCI Driver included ?

AHCI drivers are a different download pack from the chipset drivers page .. and you'll know if it's in AHCI mode by looking at device manager and your IDE ATA/ATAPI controllers settings / drivers .. and by doing some benchmarking and comparing it to IDE/SATA modes etc ..
