Dear anthonyy, Thanks for the working example. PCI\VEN_1028&DEV_0015&SUBSYS_1F011028="percsas" PCI\VEN_1028&DEV_0015&SUBSYS_1F021028="percsas" PCI\VEN_1028&DEV_0015&SUBSYS_1F031028="percsas" was not added to [HardwareIdsDatabase] by nLite. Not sure why, as it added the rest of the driver info and the drivers OK. A look at TXTSETUP.SIF showed the vital device codes were missing, as I could see it being loaded on the startup screen. Added it and the 2003x64 installer found the SAS raided disks; I recovered my registry from the repair folder and my company email server is running again! Thanks Ian
