OK, so I've slimmed down my install to about 150MB using nLite and gosh's method (yes, both of them). My unattended install works fine, except for the fact that cmdlines.txt is not getting parsed. I have my $OEM$ folder on the root of the CD. Here are the contents of my winnt.sif file: [Data] Autopartition = 0 MsDosInitiated = 0 UnattendedInstall = Yes [Unattended] UnattendMode = FullUnattended UnattendSwitch = No OemPreinstall = Yes OemSkipEula = Yes FileSystem = * WaitForReboot = No NoWaitAfterTextMode = 1 NoWaitAfterGUIMode = 1 TargetPath = Windows DriverSigningPolicy = Ignore NonDriverSigningPolicy = Ignore [Display] Xresolution = 1024 Yresolution = 768 BitsPerPel = 32 Vrefresh = 60 [GuiUnattended] EncryptedAdminPassword = No AdminPassword = "123456" TimeZone = 035 OEMSkipRegional = 1 OemSkipWelcome = 1 [Components] Indexsrv_system = Off [UserData] ProductKey = "XXXXX-XXXXX-XXXXX-XXXXX-XXXXX" ComputerName = SLIM-XP FullName = "Your Mom" OrgName = "Home" [RegionalSettings] Language = 0409 [Networking] InstallDefaultComponents = Yes [Identification] JoinWorkgroup = HOME Everything looks fine to me. OemPreinstall is set to YES, so everything in the $OEM$ folder, in theory, should do something, right? Here is my cmdlines.txt: [COMMANDS] "useraccounts.cmd" "REGEDIT32.EXE /S tweaks.reg" And my useraccounts.cmd: net user Michael nottellingyou /add net localgroup Administrators Michael /add net accounts /maxpwage:unlimited EXIT All I'm trying to do is basic stuff. Adding a user account and adding some registry tweaks. None of this happens during the install. I've tried different things for the past few days, reinstalling XP on VMware about 20 times, but NOTHING works. One more thing; All the files (cmdlines.txt, useraccounts.cmd, tweaks.reg) are in the $OEM$ folder. What am I doing wrong!?
