Hey everyone, first post on MSFN. I'm using a network share to install Windows XP SP2 with slipstreamed hotfixes and programs, no problems there, works absolutely fine on a standard IDE drive. I boot from the Windows Preinstallation Kit CD with a USB drive containing the winbom.ini file and everything installs fine. The only installation that doesn't work is the use of an SATA drive on the motherboard with a VIA VT8237 controller. I've searched the forum for answers with no luck in my particular scenario, the closest I've come related to settings to be burned onto a CD. The PE environment starts, all is OK, everything runs fine, I even get the '53 minutes remaing' Windows installation environment, files copy from my master PC, all is OK. When the system re-boots, it doesn't carry on the installation, it halts just as it tries to boot from the hard disk. If I boot from a UBCD with the VT8237 drivers, I can access the C: drive and see the files there, the root shows these: $LDR$ (file) $WIN_NT$.~BT (folder) $WIN_NT$.~LS (folder) I386 (folder) ntdetect.com (file) ntldr (file) sysprep (folder) txtsetup.sif (file) I've checked the drive is the active partition, which it is. I've tried the installation in two ways, ie. letting windows install it's own SATA drivers and installing the provided drivers, but windows stops in the same place each time. Here is what I've added to the UNATTENDED.TXT file: [MassStorageDrivers] "VIA RAID Controller(Windows XP)" = "OEM" [OEMBootFiles] viamraid.cat VIAMRAID.INF TXTSETUP.OEM viamraid.sys [Unattended] Unattendmode = FullUnattended OemPreinstall = Yes TargetPath = * Filesystem = LeaveAlone OemSkipEula = YES FactoryMode = YES OEMPnPDriversPath = "drivers\video\ati;drivers\video\km400;drivers\video\nvidia;drivers\modem\intel;drivers\audio\ac97;drivers\sata" I've installed the [OEMBootFiles] files to the $OEM$\textmode folder and to the $OEM$\$1\drivers\sata folder. As far as I'm aware, I've done everything I should to make it work, and like I mentioned to start with, it works on a standard IDE drive and not on an SATA drive. I look forward to hearing suggestions to this problem. Regards Tony
