I wanted to create an .iso with little fuss after slipstreaming SP2POEM_EN with w2ksp4_en.exe I downloaded http://unattended.msfn.org/files/CDImage_Pro.zip and used the CD boot image I'd extracted from my own SP2POEM_EN, adjusting ISO Creator for WinXP Pro.cmd accordingly, it now looks like this: --- CLS @echo off TITLE Creating ISO Image of Windows XP Professional ECHO. ECHO Removing any possible attributes set on G:\SP2POEM_EN and its subfolders... attrib -R -H G:\SP2POEM_EN /S /D ECHO. ECHO Creating ISO... CDIMAGE.EXE -lSP4POEM_EN -t12/31/2002,12:00:00 -h -j1 -m -bMicrosoftCorporation.img G:\SP2POEM_EN G:\SP4POEM_EN.iso ECHO. PAUSE EXIT --- An .iso was dumped on my HD and off I went to give it a whirl in Virtual PC, everything seems OK. Is it ok to do this? might the switches in the .cmd file be different for Win2k, or are things the same? Just curious, because it sure is a handy way of making an .iso, instead of using Nero etc...
