Windows XP X64 AHCI Driver for Asrock Z270M Pro4 in Windows XP Posted October 9 Hey. I have a problem with XP X64. I have integrated AHCI drivers with the Ntlite program. The problem I have is when it boots the installer. It pops up an error 07B. My motherboard is ASROCK Z270M PRO4. I don't know what to do next. I am very much asking for help.
