From: f0gger on 6 Jan 2008 11:38 I'm having trouble enabling AHCI under Windows Vista Business x64. I initially installed the OS with AHCI enabled in the BIOS, but I receive stop code 7B upon reboot. The only way to get the OS to boot is to disable AHCI in the BIOS. The last time I installed the OS, I was able to apply a registry patch and manually copy IaStor.sys (from the Intel Matrix Storage Manager driver) into the \Windows\System32\drivers folder. This would allow me to boot and run the system with AHCI enabled, and utilize the Intel Turbo Memory flash cache module I installed. I also made sure that Msahci.sys was set to start on boot as per the instructions at http://support.microsoft.com/kb/922976. Now, for some reason, this procedure no longer works. I still receive stop code 7B upon reboot. (Note that I am not able to install the Intel Matrix Storage Manager driver or the Intel Turbo Memory driver until after AHCI is working. Attempting to do so results in an error message that my system "does not meet the minimum requirements".) I'm trying this on a Dell Vostro 1500 with a PM965 chipset and ICH8 I/O controller hub. This is the contents of the registry file I'm using: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\CriticalDeviceDatabase\PCI#VEN_8086&DEV_2922&CC_0106] "Service"="iaStor" "ClassGUID"="{4D36E96A-E325-11CE-BFC1-08002BE10318}" [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor] "Type"=dword:00000001 "Start"=dword:00000000 "Group"="SCSI miniport" "ErrorControl"=dword:00000001 "ImagePath"="system32\\drivers\\IaStor.sys" "tag"=dword:00000019 "DisplayName"="Intel AHCI Controller" [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor\Parameters] "queuePriorityEnable"=dword:00000000 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor\Enum] "0"="PCI\\VEN_8086&DEV_2922&SUBSYS_B0051458&REV_02\\3&13c0b0c5&0&FA" "Count"=dword:00000001 "NextInstance"=dword:00000001 Any ideas?

Typical of MS to turn the solution to the driver problem into a problem itself. The fis is not to use Vista (and if you have to, you have my condolences...)
