Well, a link would have been nice.
Finally found what you're talking about. Link here:
http://www.bay12games.com/forum/index.php?topic=38274.msg649374#msg649374I've copied/pasted the data, and made the only change necessary - changing the world name to "Vanilla Dream" (instead of "NEW".)

Copy/paste that text into your DF/data/init/world_gen.txt file (it's just a .txt file, it opens with notepad or sim). Put it below everything, skip a line for readability.
Then (re)open DF, and select "
Design New World With Parameters" - select VANILLA DREAM and hit Enter.
With those values, it should generate the identical world (unless your OS is differnt re Windows/Mac/Linux.)
