I have Windows 7 x64 Ultimate, AMD Phenom II X4 20 CPU, Gigabyte GA-MA790XT-UD4P motherboard.
AHCI mode was working just fine when I first installed the SSD and OS.
I enabled it in the registry via:
I don't know if changing the pciide value to 3 to disable it and leaving msahci on 0 will do the trick, but I think it will lock me out completely if the msahci mode won't work.
I don't know what else to do.
I ran driverquery in the command prompt and it says mshaci is loaded:
msahci msahci Kernel 11/20/2010 3:33:58 AM
The msahci.sys file is loading just fine. However in device mangager I noticed there is no AHCI 1.0 device there anymore and I don't know how to get that back or if that is the issue.
