Windows XP AHCI and RAID FIX

Getting AHCI working in XP
Please read the 0x0000007B stop error page for a description of the problem as it is to all intents and purposes the same. You will just need to use the below Registry file and .sys file instead.

Registry File

 * Save the registry file out (link at bottom of it) and just double click on it to import it, AFTER you have loaded the registry hives with RegeditPE. (_REMOTE_SYSTEM key is where regeditPE mounts them)


 * Make sure the following iaStor.sys From Intel Matrix Storage, available here at time of writing copied to \Windows\system32\drivers


 * Check HKEY_LOCAL_MACHINE\_REMOTE_SYSTEM\Select\Current is DWORD 0x00000001 to make sure ControlSet001 is correct and if not search & replace in the registry file to change it (to say ControlSet002) if 'Current' DWORD value is 0x00000002

Getting RAID working in XP
As above...Intel RAID (aka 'fake RAID', outside of the Windows world) also has same issues with the same fix. It needs the same iaStor.sys copying too and the Service is the same. Note the only real difference is using a difference Class 4D36E97B-... instead of 4D36E96A-...

Registry File
Again, the same - this time use the below registry file and same iaStor.sys as above
