Full Install

So here's a general question. I know originally the FPSPKG was for software upgrade only, and the Iso image was to do a full install, which also resulted in wiping out all the shows.

My memory is that part of the BIOS 17 implementation was a partitioning of the hard disk so that the full install would not always wipe out all the show files.

So, is my memory incorrect? Did things get changed so a full install also wipes out the data on the second partition? what's really going on with the HDD and the full install?
