How to make Vista List Image?

i have a vista dvd oem by dell.

i've delete PID.txt on folder source, also on Boot.wim

also edit Setup.cfg

now my vista installer have to put serial key in order to install which Vista Edition to install.

i use vlite to slipstream SP1 to Vista Home, Vista Home Premium, Vista Bussines, and Vista Ultimate.

so in 1 cd installer of mine, have those 4 installer vista.

i edit Installer.wim to delete 2 premium image.

so i have to put serial number to which Vista edititon that i want to install.

now my question, i have all the serial for those 4 vista edition.

can i make those serials to put on the cd and when i want to install, i only have to select which version of vista to install?

i see on of my vista installer that have 32bit and 64bit Vista Ultimate. it has the option to select which version to install.

how to make those option?
