Hi, I have been suffering with the same problem. Check that the disk names match up between the [Disks] and [Files.....] sections - highlighted in bold below. [Disks] d1 = "Dell SAS 5x and SAS 6x Controller Driver (Windows XP 32-bit)", symmpi.sys, \ [scsi] DELL_SAS = "Dell SAS 5x and SAS 6x Controller Driver (Windows XP 32-bit)" [Files.scsi.DELL_SAS] driver = d1,symmpi.sys,SYMMPI inf = d1,symmpi.inf inf = d1,delpseud.inf catalog = d1,mpixp32.cat I hope this helps.
