Started in '97 when Aperture was desperate for an easier way of controlling GLaDOS. So our scientists thought up of a GUI solution. The solution was based on a 32-bit method, using a protected-mode processor. We could make the GUI solution easier, faster and more secure. This essentially reduced the text portion of GLaDOS to being a Bootloader. As with some of our design goals, We aimed to having longer filenames. How this worked is that we had the filenames in a separate buffer and it would use a system call to call up the different name.
