Toshiba have now got raid controllers in some of their laptops (we have a few Portege M400's) and i have the misfortune of getting them working with RIS. I have spent hour upon hour scouring the web for information and have tried countless different configurations of .sif file and $OEM$ folder structures. It always comes back to the same sort of errors for me though: File txtsetup.oem caused an unexpected error (21) at line 1742 in d:\xpsp1\base\boot\setup\oemdisk.c. Press any key to continue. Is the latest one from using method 2 and adding a few extra folders everywhere . Here's my riprep.sif file: [data] floppyless = "1" msdosinitiated = "1" OriSrc = "\\%SERVERNAME%\RemInst\%INSTALLPATH%\%MACHINETYPE%" OriTyp = "4" LocalSourceOnCD = 1 DisableAdminAccountOnDomainJoin = 0 UnattendedInstall = "Yes" [SetupData] OsLoadOptions = "/noguiboot /fastdetect" SetupSourceDevice ="\Device\LanmanRedirector\%SERVERNAME%\RemInst\%INSTALLPATH%" SysPrepDevice="\Device\LanmanRedirector\%SERVERNAME%\RemInst\%SYSPREPPATH%" SysPrepDriversDevice="\Device\LanmanRedirector\%SERVERNAME%\RemInst\%SYSPREPDRIVERS%" [Unattended] UnattendMode = DefaultHide UnattendSwitch = "yes" OemPreinstall = yes FileSystem = LeaveAlone ExtendOEMPartition = 0 TargetPath = \WINDOWS OemSkipEula = Yes InstallFilesPath = "\\%SERVERNAME%\RemInst\%INSTALLPATH%\%MACHINETYPE%" LegacyNIC = 1 DriverSigningPolicy = Ignore [MassStorageDrivers] "TOSHIBA RAID Driver for Windows XP" = "OEM" "IDE CD-ROM (ATAPI 1.2)/PCI IDE Controller" = "RETAIL" [OEMBootFiles] TXTSETUP.OEM kr10n.inf kr10n.cat kr10n.SYS kr10n virtual.inf [UserData] FullName = "Admin" OrgName = "******" Computername = "%MACHINENAME%" ProductKey = "*********************" [Identification] JoinDomain = ******** ;DoOldStyleDomainJoin = Yes DomainAdmin = "***" DomainAdminPassword = "******" [GuiUnattended] OemSkipWelcome = 0 OemSkipRegional = 1 TimeZone = 85 Adminpassword = ******** [Networking] [NetServices] MS_Server=params.MS_PSched [RemoteInstall] Repartition = Yes UseWholeDisk = Yes [OSChooser] Description ="Toshiba M400" Help ="" LaunchFile ="%INSTALLPATH%\%MACHINETYPE%\templates\startrom.com" ImageType =SYSPREP Version="5.1 (2600)" SysPrepSystemRoot="Mirror1\UserData\WINDOWS" HalName=halmacpi.dll ProductType=0 The drivers are in the following folders: D:\RemoteInstall\Setup\English\Images\ToshM400\i386\$OEM$ D:\RemoteInstall\Setup\English\Images\ToshM400\i386\$OEM$\TEXTMODE D:\RemoteInstall\Setup\English\Images\ToshM400\i386\$OEM$\$$\OEMDIR (pretty sure this isnt relevant but am getting desperate) Does anyone have any ideas? Thanks in advance.
