Hi all I hope that anyone will have an idea why my unattended Windows installation CD doesn't reconize my HDD. I have a CD that I splitstream the major brand SataRaid drivers (via, intel and nVidia). The Via woks fine. The problem I have is with my Nvidia. I have donwloaded the drivers from MSI (My board it the K9N Neo) and I put the drivers in the $OEM$\$1\Drivers\nvidia 's folder. I added this path without the $OEM$\$1 to the winnt.sif file. OemPnPDriversPath="drivers\vmware;Drivers\nvidia;Drivers\3112;Drivers\3114;Drivers\intel;Drivers\intel2;Drivers\via;Drivers\promise;Drivers\sis;Drivers\ite" In txtsetup.sif, I add the following lines: [HardwareIds.scsi.RAIDCLASS] id = "GenNvRaidDisk","nvraid" id = "*_NVRAIDBUS","nvraid" id = "*NVRAIDBUS","nvraid" [HardwareIds.scsi.BUSDRV] id = "PCI\VEN_10DE&DEV_008E", "nvatabus" id = "PCI\VEN_10DE&DEV_00D5", "nvatabus" id = "PCI\VEN_10DE&DEV_00EE", "nvatabus" id = "PCI\VEN_10DE&DEV_00E3", "nvatabus" id = "PCI\VEN_10DE&DEV_0036", "nvatabus" id = "PCI\VEN_10DE&DEV_003E", "nvatabus" id = "PCI\VEN_10DE&DEV_0054", "nvatabus" id = "PCI\VEN_10DE&DEV_0055", "nvatabus" id = "PCI\VEN_10DE&DEV_0266", "nvatabus" id = "PCI\VEN_10DE&DEV_0267", "nvatabus" id = "PCI\VEN_10DE&DEV_036F", "nvatabus" id = "PCI\VEN_10DE&DEV_037E", "nvatabus" id = "PCI\VEN_10DE&DEV_037F", "nvatabus" id = "PCI\VEN_10DE&DEV_03F6", "nvatabus" id = "PCI\VEN_10DE&DEV_03F7", "nvatabus" id = "PCI\VEN_10DE&DEV_03E7", "nvatabus" [scsi.load] RAIDCLASS = nvraid.sys,4 BUSDRV = nvatabus.sys,4 .... [sCSI] RAIDCLASS = "NVIDIA RAID CLASS DRIVER (required)" BUSDRV = "NVIDIA nForce Storage Controller (required)" ... [sourceDisksFiles] nvatabus.sys = 1,,,,,,4,4,1,,,1,4 nvraid.sys = 1,,,,,,4,4,1,,,1,4 nvraid.inf = 1,,,,,,,20,0,0 ... I have copied the three files in the sourcedisksfiles section into the i386 folder and renamed the extension to replace the last letter by an "_" Upon boot-up, the installation goes through the loading phase without errors ( I even see the two Nvidia going through). At the end, the screen flicks and I get the error message that Windows didn't find any Hard disk. What the hell is the problem. I know that the drivers are good because I put them on a floppy, boot with an old standard XP SP1 CD, presssed F6 and I was able to install XP on my machine. I am usualy able to dig up solution but this one made me hit the bottom. I really don't know what it is. Please help Thanks
