When cmdlines.txt is runned?

[kalavera]

I have a xp unattended cd with 3 options, retail, unattended (just winnt.sif) and full unattended (winnt.sif + patches, hotfixes, progs)

Right now i'm using cmdlines.txt to run runonceex commands and install everything.

All ok, but the problem is when choosing the second option in the cd ... the winnt.sif used in option 2 only differs from option 3 with the switch OemPreinstall=No

What i have discovered is that even then the $OEM$ files are processed ! And i don't want that way when choosing option 2.

How can i do it?

BTW: i don't want to copy install files to disk ... so i'm using the cdrom script in my cmd files.
