Hi
I have asrock 785gxh chipset with sb710. Need help on enabling AHCI mode in xp(already installed).
I have tried the below method but didnt work (BSOD).
:S:S:S
1. at IDE MODEL Copy ?ahcix86.sys? to x:/WINDOWS/system32/drivers/

2. Regedit

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CriticalDeviceDatabase\pci#ven_1002&dev_4353]
"ClassGUID"="{4D36E97D-E325-11CE-BFC1-08002BE10318}"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CriticalDeviceDatabase\pci#ven_1002&dev_4391]
"Service"="ahcix86"
"ClassGUID"="{4D36E97B-E325-11CE-BFC1-08002BE10318}"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ahcix86]
"Type"=dword:00000001
"Start"=dword:00000000
"Group"="SCSI miniport"
"ErrorControl"=dword:00000001
"ImagePath"="system32\\drivers\\ahcix86.sys"
"Tag"=dword:00000001

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ahcix86\Parameters]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ahcix86\Parameters\Device]
"NumberOfRequests"=dword:00000080

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ahcix86\Parameters\PnpInterface]
"5"=dword:00000001

you can Copy all about above to Notepad save as *.reg easy to registy.

3. Reboot enter to BIOS change to AHCI MODE
