I have decided to produce the unattended cd\dvd manually rather than using nLite. I think this will be easier to maintain/update. Can you please check/vet the following steps? 1. Integrate SP3 into XPSP2_EN using E:\ WindowsXP-KB936929-SP3-x86-ENU.exe /integrate:E:\XPSP2_EN 2. Create a $OEM$ folder structure, say in E: 3. Place all applications to be installed in \$OEM$ \$1\Install (in sub dirs) 4. Place relevant (unpacked) drivers in \$OEM$ \$1\Drivers 5. Copy contents of \$OEM$ \$1\Install to XPSP3_EN \$OEM%\$1\Install 6. Copy contents of \$OEM$ \$1\Drivers to XPSP3_EN \$OEM%\$1\Drivers 7. Create a directories \$OEM$\$Progs\Netmeter, \$OEM$\$Progs\Ccleaner etc containing the ini and application data files such as NetMeter.tlg 8. Create (manually) a Winnt.sif and place in XPSP3_EN\I386 9. In Winnt.sif (among other things) place [unattended] DriverSigningPolicy=Ignore OemPnPDriversPath="drivers\01_ChipSet" (dir containing the .inf) [GuiRunOnce] %systemdrive%\My_Start.cmd (I had placed the My_Start.cmd under $1) 10. Create the My_Start.cmd file and place in \$OEM$\$1 11. Use CDImageGUI to create the bootable iso 12. Burn the iso with Nero (as image) Note 1 I intend to treat IE8, WMP11, and Silverlight etc as applications with their own updates. If I miss an update, I’ll let Microsoft Update handle it. Note 2 My_Start.cmd with invoke other cmd files for installation, cleanup, post processing (after rebooting). Thank you.
