Was wondering if in Server2008.iso there is a file that can be removed/altered to allow choice of any version to install, similar to win 7 ei.cfg. Is this possible? I have Server2008 Enterprise but was just curious.For example, Foundation,Standard,Enterprise,DataCenter, or Web
You can change a retail into a OEM, by modifying the ei.cfg, or the other way around. To my knowledge, that is as far as it goes. Did it myself last week, with original CDIMAGE and right parameters, you can make a retail / OEM ISO with right original checksum. If they were all the same size as Windows 7 is, apart from enterprise vol and pro vol, you probably could. But they are not.
The links that I've posted earlier have All in one image in 6 different languages straight from MS. That win7 trick does not work but if you want all of those editions you can DL an AIO image instead.
