Can someone please explain to me what I am doing wrong. I am trying to downgrade from windows vista to xp and I am having trouble due to my Sata HDD I guess. Everytime I try and load the slipstreamed cd with the drivers for the hard drive I get the Blue screen of death saying that windows will now shut down to prevent any damage to the computer. Also these error codes pop up: 0x0000007B (0xF7A56524, 0xC0000034, 0x00000000) This is what I have added into TXTSETUP.SIF TXTSETUP.SIF [SourceDisksFiles] iaStor.sys = 1,,,,,,x_,4,1 [HardwareIdsDatabase] PCI\VEN_8086&DEV_2653&CC_0106 = "iaStor" PCI\VEN_8086&DEV_2681&CC_0106 = "iaStor" PCI\VEN_8086&DEV_27C1&CC_0106 = "iaStor" PCI\VEN_8086&DEV_27C5&CC_0106 = "iaStor" PCI\VEN_8086&DEV_2821&CC_0106 = "iaStor" PCI\VEN_8086&DEV_2829&CC_0106 = "iaStor" PCI\VEN_8086&DEV_2922&CC_0106 = "iaStor" PCI\VEN_8086&DEV_5029&CC_0106 = "iaStor" PCI\VEN_8086&DEV_2653&CC_0106 = "iaStor" PCI\VEN_8086&DEV_2681&CC_0106 = "iaStor" PCI\VEN_8086&DEV_27C1&CC_0106 = "iaStor" PCI\VEN_8086&DEV_27C5&CC_0106 = "iaStor" PCI\VEN_8086&DEV_2821&CC_0106 = "iaStor" PCI\VEN_8086&DEV_2829&CC_0106 = "iaStor" PCI\VEN_8086&DEV_2922&CC_0106 = "iaStor" PCI\VEN_8086&DEV_5029&CC_0106 = "iaStor" [SCSI.Load] iaStor = iaStor.sys,4 [SCSI] iaStor = "Intel(R) ICH8M SATA AHCI Controller" This is what my WINNT.SIF file looks like [Data] AutoPartition=0 MsDosInitiated="0" UnattendedInstall="Yes" [Unattended] UnattendMode=ProvideDefault OemPreinstall=Yes OemSkipEula=Yes NoWaitAfterTextMode=1 NoWaitAfterGUIMode=1 WaitForReboot="No" TargetPath=WINDOWS DriverSigningPolicy=Ignore OemPnPDriversPath=drivers\Sata [GuiUnattended] OEMSkipWelcome = 1 [UserData] ProductKey=xxxx-xxx-xxxxx-xxx FullName="Brad" OrgName="" I added my .sys file into the i386 folder (which is named iaStor.sys) The added drivers are in this directory c:\WinSata\$OEM$\$1\drivers\Sata I'm not sure if I am missing anything but I have tried again and again changing little things and I can't seem to get this to work. The cds boot up whenever the OS is loaded but when I try and restart the computer and load the cd the blue screen pops up. If anyone can help me I would be greatly appreciated.
