You need to look into a 3rd party installer for all of your apps like xplode, wihu or WPI (all can be found on this forum) WPI's main site can be found in my sig. This way you have your os on one disk with a script to call for the install wrapper using yet another ap like cdswitch or just manually switching the cds at the right time. WPI is actually very simple to configure and has a very easy to customize interface (see the themes page) WPI and cdswitch are both free and open to use for corporate use, please remember to try to donate if your find them really usefull. Cdswitch --> http://www.msfn.org/board/Cd-switching-Uti...amp;hl=cdswitch You can also find a version of cdswitch in the WPI tools package that has a couple of WPI-ish themes with it.
